I have a SEO URL like
lieferservice-pizzeria-da-persio-26-offenbach
in my bootstrap file I am trying to pase this URL and get ID of a shop which is in this is 26
Then I can read the database to get infos of the shop. What will be the best way to do this. have no idea.
The proposed solution simply removes all non digits so you end up with only digits. This works if you can ensure that you'll never have a digit in your string else than the string. So with a string like 'lieferservice-pizzeria12-da-24-persio-26-offenbach' you would get 122426 instead of the 26 you wanted to.
If you want to ensure that you only accept -somedigit- as id you should use:
preg_match("/-([0-9]+)-/", $input_line, $output_array);
instead.
What this actually does is really simple:
It simply looks for the first string starting with a "-" followed by exclusive! digits and ending with "-" than it returns the whole string in $output_array[0] (in your example -26-) and the digit (the stuff inside the brackets) in $output_array[1] which equals 26 in your case.
that's what routes are for. you can paramatized any part of url and access it in the request.in your case i think you want to combine some sort of a slug with an id separted by dash. that's a piece of cake.
Router::connect('/:slug-:id', array('controller' => 'yourController', 'action' => 'yourAction'), array('id' => '[0-9]+','slug' => '[a-zA-z-]+'));
//inside your action
$id = $this->request->params['id'];
$slug = $this->request->params['slug'];
no nee for regex :)
Best Solution
$str = 'lieferservice-pizzeria-da-persio-26-offenbach';
$int = intval(preg_replace('/[^0-9]+/', '', $str), 10);
var_dump($int );
Its return only int 26
Assuming you have a function in your controller, let call it
public function getUrl(){
}
The first think is to make CakePhp accept the type of URL you are passing (with special characters like "-"). In your route you can have this:
Router::connect('/getUrl/:id', array('controller' => 'yourControllerName', 'action' => 'getUrl'), array('id' => '[0-9A-Za-z= -]+'));
Now if you pass your URL as
www.domain.com/getUrl/lieferservice-pizzeria-da-persio-26-offenbach
Then back to your function
public function getUrl(){
$getValueFromUrl = $this->params['id'];
// Use PHP explode function to get 26 out of $getValueFromUrl
}

I started fiddling with Prestashop 1.7 modules and I ran into this weird behavior.
I have this code to save values from form post to database (working ok)
protected function postProcess()
{
$form_values = $this->getConfigFormValues();
foreach (array_keys($form_values) as $key) {
Configuration::updateValue($key, Tools::getValue($key));
if($key == 'MSLT_MEGAMENU_CATEGORIES'){
$categories = implode(",",Tools::getValue($key));
Configuration::updateValue('MSLT_MEGAMENU_CATEGORIES', $categories);
}else{
$this->errors[]=$this->l('Please select categories to display');
}
}
}
And I use this code to fetch those values from database (works ok)
protected function getConfigFormValues()
{
$categories = explode(',',Configuration::get('MSLT_MEGAMENU_CATEGORIES', true));
return array(
'MSLT_MEGAMENU_LIVE_MODE' => Configuration::get('MSLT_MEGAMENU_LIVE_MODE', true),
'MSLT_MEGAMENU_CATEGORIES' => $categories,
'MSLT_MEGAMENU_ACCOUNT_EMAIL' => Configuration::get('MSLT_MEGAMENU_ACCOUNT_EMAIL', 'contact#prestashop.com'),
'MSLT_MEGAMENU_ACCOUNT_PASSWORD' => Configuration::get('MSLT_MEGAMENU_ACCOUNT_PASSWORD', null),
);
}
and helper to populate form with values
$helper->tpl_vars = array(
'fields_value' => $this->getConfigFormValues(), /* Add values for your inputs */
'languages' => $this->context->controller->getLanguages(),
'id_language' => $this->context->language->id,
);
return $helper->generateForm(array($this->getConfigForm()));
This is the var_dump() when trying to load values from database, for this case my DB value is (1,3,9)
array(1) { [0]=> string(1) "9" }
As you can see Configuration::get() only gets the last string value.
Interesting behavior is that when I update the data and stay in the same page, then everything is ok and data is fetched properly, but when I leave module configuration page and comeback, the issue happens. Maybe I am missing some little snippet of code? I am still a newbie. If needed I can provide more code.
I don't know what your specific goal is but in any case it is always convenient to use Prestashop's own functions.
To save and select the configuration variables
eg, save values in json format
Configuration::updateValue('MYVALUES', Tools::jsonEncode(Tools::getValue('MYVALUES')), true );
eg, get values
Tools::jsonDecode( Configuration::get( 'MYVALUES' );
Dirty workaround I found to get imploded values from DB correctly. Maybe someone will use it.
$sql = 'SELECT * FROM '._DB_PREFIX_.'configuration WHERE name = "MSLT_MEGAMENU_SELECTED_CAT"';
$value = Db::getInstance(_PS_USE_SQL_SLAVE_)->getRow($sql);
$selected = explode(',',$value['value']);
I’m a beginner in Laravel but have a problem at first. I wrote this query and I’m waiting for Sonya Bins as result but unexpectedly I see ["Sonya Bins"]. what’s the problem?
Route::get('products', function () {
$articles=DB::table('users')->where('id','2')->get()->pluck('name');
return view('products',compact('articles'));
});
pluck will return array if you want to get only single value then use value
// will return array
$articles=DB::table('users')->where('id','2')->get()->pluck('name');
//will return string
$articles=DB::table('users')->where('id','2')->value('name');
// output Sonya Bins
here is an example from the documentation:
if you don't even need an entire row, you may extract a single value from a record using the value method. This method will return the value of the column directly:
$email = DB::table('users')->where('name', 'John')->value('email');
Read more about it here
Hope it helps.
Thanks
pluck() used to return a String before Laravel 5.1, but now it returns an array.
The alternative for that behavior now is value()
Try this:
Route::get('products', function () {
$articles=DB::table('users')->where('id','2')->get()->value('name');
return view('products',compact('articles'));
});
I think it's easier to use the Model + find function + value function.
Route::get('products', function () {
$articles = User::find(2)->value('name');
return view('products',compact('articles'));
});
pluck will return the collection.
I think id is your primary key.
You can just get the first record, and call its attribute's name:
DB::table('users')->where('id','2')->first()->name;
or
DB::table('users')->find(2)->name;
First thing is that you used invalid name for what you pass to view - you don't pass articles but user name.
Second thing is that you use get method to get results instead of first (or find) - you probably expect there is only single user with id = 2.
So to sum up you should use:
$userName = DB::table('users')->find(2)->name;
return view('products',compact('userName'));
Of course above code is for case when you are 100% sure there is user with id = 2 in database. If it might happen there won't be such user, you should use construction like this:
$userName = optional(DB::table('users')->find(2))->name;
($userName will be null if there is no such record)
or
$userName = optional(DB::table('users')->find(2))->name ?? 'No user';
in case you want to use custom string.
By default , cakephp would return empty array on find() when nothing founded.
but how to set it to show as blank array.
For example:
$customer = $this->Transaction->Customer->find(--conditions to return 0 result.--)
I want it to show as blank array like this.
array('Customer' => array('customer_id'=>null, 'name'=>null, 'lastname'=>null))
not just empty one like
array() or null
because I always got error shown in view that $customer['Customer']['name'] is undefined index. and I don't like to use isset() or is_null() to check before every time.
Use the afterFind callback method in your model. Something like this:
public function afterFind($results, $primary = false) {
if (empty($results)) {
$results = array('Customer' => array('customer_id'=>null, 'name'=>null, 'lastname'=>null))
}
return $results;
}
http://book.cakephp.org/2.0/en/models/callback-methods.html
If you really want/need to do this, you can use something like:
$default = array('Customer' => array('customer_id' => null, 'name'=>null, 'lastname' => null));
$customer = $this->Transaction->Customer->find(...)
$customer = array_merge($default, $customer);
This way, if the result is empty, it will use your default values.
However, this is not a good practice, because you might end up displaying "Welcome, NULL", in the page. You should use if (!empty($customer)) ... in your view.
Also, in this example, are you using find->('first') ?
I have a small problem. I am making a site that has Tags and Questions. I have a Question model, Tag model, QuestionsTag model, everything fits together nicely. The user upon asking something puts the tags in the field seperated by a space (foo bar baz) much like on stackoverflow.com.
Now, here is the code to check if a tag already exists or not and entering the tag into the database and the required associations:
function create () {
if (!empty($this->data)) {
$this->data['Question']['user_id'] = 1;
$question = $this->Question->save ($this->data);
/**
* Preverimo če se je vprašanje shranilo, če se je,
* vprašanje označimo.
*/
if ($question) {
$tags = explode (' ', $this->data['Question']['tags']);
foreach ($tags as $tag){
if (($tagId = $this->Tag->existsByName($tag)) != false) {
/**
* Značka že obstaja, torej samo povezemo trenuten
* id z vprašanjem
*/
$this->QuestionsTag->save (array(
'question_id' => $this->Question->id,
'tag_id' => $tagId
));
}
else {
/**
* Značka še ne obstaja, jo ustvarimo!
*/
$this->Tag->save (array(
'name' => $tag
));
// Sedaj pa shranimo
$this->QuestionsTag->save(array(
'question_id' => $this->Question->id,
'tag_id' => $this->Tag->id
));
$this->Tag->id = false;
}
; }
}
}
}
The problem is this, a Question has an id of 1 and I want it to have the tags with id of 1, 2, 3.
When the 2nd and 3rd save get called, Cake sees that in the questions_tags table is already a question with id 1, so it just updates the tag.
But this is not correct, as there should be many questions in that table with the same id, as they refer to different tags belonging to them.
So, is there a way to prevent this? Prevent the save method from UPDATEing?
Thank you!
This behavior isn't specific to HABTM relationships. You are calling the save() method inside of a loop. After the first save, an id value is set and each subsequent save call sees the id and assumes it's an update. Within a loop, you first need to call model->create() to reset an id value that may exist.
From the CakePHP Docs at http://book.cakephp.org/view/75/Saving-Your-Data:
When calling save in a loop, don't forget to call create().
In your case, it would look like this:
$this->QuestionsTag->create();
$this->QuestionsTag->save (array(
'question_id' => $this->Question->id,
'tag_id' => $tagId
));
Check out saveAll. You can make a single call to $this->Question->saveAll(), and it will save any associated data you supply as well. Note that with HABTM data, it will perform a DELETE for any questions_tags associated with that question_id, then perform an INSERT for all the tag_id's included with your data.
if you want to make sure, that a new entry (INSERT) is made rather then an update, you can set $this->create(); right in front of the save call. See http://book.cakephp.org/view/75/Saving-Your-Data (in the upper part of the page): When calling save in a loop, don't forget to call create().
I have an array called $all_countries following this structure:
Array
(
[0] => Array
(
[countries] => Array
(
[id] => 1
[countryName] => Afghanistan
)
)
[1] => Array
(
[countries] => Array
(
[id] => 2
[countryName] => Andorra
)
)
)
I want to loop through an array called prohibited_countries and unset the entire [countries] element that has a countryName matching.
foreach($prohibited_countries as $country){
//search the $all_countries array for the prohibited country and remove it...
}
Basically I've tried using an array_search() but I can't get my head around it, and I'm pretty sure I could simplify this array beforehand using Set::extract or something?
I'd be really grateful if someone could suggest the best way of doing this, thanks.
Here's an example using array_filter:
$all_countries = ...
$prohibited_countries = array('USA', 'England'); // As an example
$new_countries = array_filter($all_countries, create_function('$record', 'global $prohibited_countries; return !in_array($record["countries"]["countryName"], $prohibited_countries);'));
$new_countries now contains the filtered array
Well first of all id e teh array in the format:
Array(
'Andorra' => 2,
'Afghanistan' => 1
);
Or if you need to have the named keys then i would do:
Array(
'Andorra' => array('countryName'=> 'Andorra', 'id'=>2),
'Afghanistan' => array('countryName'=> 'Afghanistan', 'id'=>1)
);
then i would jsut use an array_diff_keys:
// assuming the restricted and full list are in the same
// array format as outlined above:
$allowedCountries = array_diff_keys($allCountries, $restrictedCountries);
If your restricted countries are just an array of names or ids then you can use array_flip, array_keys, and/or array_fill as necessary to get the values to be the keys for the array_diff_keys operation.
You could also use array_map to do it.
Try something like this (it's probably not the most efficient way, but it should work):
for ($i = count($all_countries) - 1; $i >= 0; $i--) {
if (in_array($all_countries[$i]['countries']['countryName'], $prohibited_countries) {
unset($all_countries[$i]);
}
}
If you wanted to use the Set class included in CakePHP, you could definitely reduce the simplicity of your country array with Set::combine( array(), key, value ). This will reduce the dimensionality (however, you could do this differently as well. It looks like your country array is being created by a Cake model; you could use Model::find( 'list' ) if you don't want the multiple-dimension resultant array... but YMMV).
Anyway, to solve your core problem you should use PHP's built-in array_filter(...) function. Manual page: http://us3.php.net/manual/en/function.array-filter.php
Iterates over each value in the input
array passing them to the callback
function. If the callback function
returns true, the current value from
input is returned into the result
array. Array keys are preserved.
Basically, pass it your country array. Define a callback function that will return true if the argument passed to the callback is not on the list of banned countries.
Note: array_filter will iterate over your array, and is going to be much faster (execution time-wise) than using a for loop, as array_filter is a wrapper to an underlying C function. Most of the time in PHP, you can find a built-in to massage arrays for what you need; and it's usually a good idea to use them, just because of the speed boost.
