The variable:
$products_in_cart = '112,109,106';
The query_posts:
query_posts(array(
'post_type' => 'product',
'post__not_in' => array($products_in_cart),
...
If I replace in the query $products_in_cart by 112,109,106 it work.
The variable is ok outside the loop, can’t understand what is wrong with this basic use, thanks for your help.
You have to pass an array of IDs to post__not_in. If you start with a comma delimited string you can use the PHP function explode to expand it to an array:
...
'post__not_in' => explode(",", $products_in_cart),
...
Because you need an array on 'post__not_in' and you are creating an array but with one input: '112, 109, 106'. You have to use the explode function. Something like this:
$products_in_cart = '112,109,106';
And then:
'post__not_in' => explode(",", $products_in_cart),
Or just create an array from the beginning:
$products_in_cart = array(112, 109, 106);

so I took a curl output of a json formatted output and assigned it to a variable.
my $catcherJSON = decode_json $response->content;
print Dumper $catcherJSON;
When I view the $catcherJSON, I want to see an array of hashes, but I just get a massive string of json.
$VAR1 = [
{
'priority' => 5,
'ingestPath' => '/vg/24CHVOD_en',
...
...
...
},
{
'priority' => 5,
'ingestPath' =>
...
...
},
{
'priority' => 5,
'ingestPath' =>
...
...
},
{
'priority' => 5,
'ingestPath' =>
...
...},
{
'priority' => 5,
'ingestPath' =>
....
...
}
];
The hashes repeat (There are about 300 unique results) and I'm trying to figure out in perl how I can split this 1 string into my array of hashes simply.
Any way that I can easily convert this into a proper array of hashes so I can iterate through it?
Thanks in advance.

You've already done it.
so I took a curl output of a json formatted output and assigned it to a variable.
my $catcherJSON = decode_json $response->content;`
That's not correct.
You took the JSON formatted string from $response->content, decoded the JSON into a Perl data structure, and stored it in $catcherJSON.
When I view the $catcherJSON, I want to see an array of hashes, but I just get a massive string of json.
$catcherJSON is not a string of JSON. $catcherJSON is a Perl array of hashes. You've already decoded the JSON into a Perl data structure with decode_json. It's been formatted by Dumper() back into Perl code so you can read it.
Your code is fine, you have what you want. For example, $catcherJSON->[0]{ingestPath} will be '/vg/24CHVOD_en'.
my $catcherJSON = $response->content;
$catcherJSON =~ s/\n//g;
$catcherJSON = decode_json($catcherJSON);
This was my eventual solution.
When the curl response comes in, all json has line breaks. As soon as line breaks are removed, my decode_json will now refence all as $catcherJSON->[0]{id}, etc...
Thanks everyone for the help here.
Much appreciated.
I have the following code:
print Dumper($dec_res->{repositories}[0]);
print Dumper($dec_res->{repositories}[1]);
my #repos = ($dec_res->{repositories});
print scalar #repos . "\n";
and the output is the following:
$VAR1 = {
'status' => 'OK',
'name' => 'apir',
'svnUrl' => 'https://url.whatever/svn/apir',
'id' => 39,
'viewvcUrl' => 'https://url.whatever/viewvc/apir/'
};
$VAR1 = {
'status' => 'OK',
'name' => 'CCDS',
'svnUrl' => 'https://url.whatever/svn/CCDS',
'id' => 26,
'viewvcUrl' => 'https://url.whatever/viewvc/CCDS/'
};

So my question is why $dec_res->{repositories} is clearly an array but #repos is not?
Here I printed the size but even trying to access elements with $repos[0] still returns an error.
Dumping $repos[0] actually print the whole structure... like dumping $dec_res->{repositories}
$dec_res->{repositories} is clearly an array
It isn't. It is an array reference.
but #repos is not?
It is an array.
You are creating a list that is one item long, and that item is the array reference. You then assign the list to the array, so the array holds that single item.
You need to dereference the array instead.
my #repos = #{$dec_res->{repositories}};
perlref explains more about references in Perl.
Dear fellow perl programmers,
I wanted to access to this array
my #vsrvAttribs = qw(
Code
Description
vsrv_id
vsrv_name
vsrv_vcpu_no
vsrv_vmem_size
vsrv_vdspace_alloc
vsrv_mgmt_ip
vsrv_os
vsrv_virt_platf
vsrv_owner
vsrv_contact
vsrv_state
);
through a variable composed of a variable and a string suffix, which of course led to the error message like this
Can't use string ("#vsrvAttribs") as an ARRAY ref while "strict refs" in use at cmdbuild.pl line 262.`
Therefore I decided to get the reference to the array through a hash
my %attribs = ( vsrv => #vsrvAttribs );
And this is the code where I need to get the content of aforementioned array
foreach my $classTypeKey (keys %classTypes) {
my #attribs = $attribs{$classTypeKey};
print Dumper(\#attribs);
}
It seems I can get the reference to the array #vsrvAttribs, but when I checked the content of the array with Dumper , the array have got only one element
$VAR1 = [
'Code'
];
Do you have any idea where could be the problem?
How do you store the array in a hash and access it later?
You need to store your array by reference like this:
my %attribs = ( vsrv => \#vsrvAttribs );
Note the backslash before the # sigil. This tells perl that you want a reference to the array.
Then when access the array stored in $attribs{vsrv} you need to treat it as a reference instead of as an array. You'll do something like this:
foreach my $classTypeKey (keys %classTypes) {
# make a copy of the array by dereferencing
my #attribs = #{ $attribs{$classTypeKey} };
# OR just use the array reference if profiling shows performance issues:
my $attribs = $attribs{$classTypeKey}
# these will show the same thing if you haven't done anything to #attribs
# in the interim
print Dumper(\#attribs);
print Dumper($attribs);
}
Why did you only get one value and where did the rest of the array go?
Your missing values from #vsrvAttribs weren't lost they were assigned as keys and values to %attribs itself. Try adding the following just after you made your assignment and you'll see it for yourself:
my %attribs = ( vsrv => #vsrvAttribs );
print Dumper(\%attribs);
You'll see output like this:
$VAR1 = {
'vsrv_contact' => 'vsrv_state',
'vsrv_virt_platf' => 'vsrv_owner',
'vsrv' => 'Code',
'vsrv_name' => 'vsrv_vcpu_no',
'vsrv_mgmt_ip' => 'vsrv_os',
'Description' => 'vsrv_id',
'vsrv_vmem_size' => 'vsrv_vdspace_alloc'
};
This is because perl interpreted your assignment by expanding the contents #vsrvAttribs as multiple arguments to the list literal ():
my %attribs = (
# your key => first value from array
vsrv => 'Code',
# subsequent values of the array
Description => 'vsrv_id',
vsrv_name => 'vsrv_vcpu_no',
vsrv_vmem_size => 'vsrv_vdspace_alloc',
vsrv_mgmt_ip => 'vsrv_os',
vsrv_virt_platf => 'vsrv_owner',
vsrv_contact => 'vsrv_state',
);
This is legal in perl and there are reasons where you might want to do this but in your case it wasn't what you wanted.
Incidentally, you would have been warned that perl was doing something that you might not want if you had an even number of elements in your array. Your 13 elements plush the hash key "vsrv" makes 14 which is even. Perl will take any list with an even number of elements and happily make it into a hash. If your array had another element for 15 elements total with the hash key you would get a warning: Odd number of elements in hash assignment at foo.pl line 28.
See "Making References" and "Using References" in perldoc perlreftut for more information.
If you use a bare array in a hash definition like
my %attribs = ( vsrv => #vsrv_attribs )
the array is expanded and used as key/value pairs, so you will get
my %attribs = (
vsrv => 'Code',
Description => 'vsrv_id',
vsrv_name => 'vsrv_vcpu_no',
vsrv_vmem_size => 'vsrv_vdspace_alloc',
...
)
The value of a Perl hash element can only be a scalar value, so if you want an array of values there you have to take a reference, as shown below
It is also a bad idea to use capitals in Perl identifiers for anything except globals, such as package names. Local names are conventional lower-case alphanumeric plus underscore, so $class_type_key instead of $classTypeKey
use strict;
use warnings;
use Data::Dumper;
my #vsrv_attribs = qw(
Code
Description
vsrv_id
vsrv_name
vsrv_vcpu_no
vsrv_vmem_size
vsrv_vdspace_alloc
vsrv_mgmt_ip
vsrv_os
vsrv_virt_platf
vsrv_owner
vsrv_contact
vsrv_state
);
my %attribs = (
vsrc => \#vsrv_attribs,
);
for my $class_type_key (keys %attribs) {
my $attribs = $attribs{$class_type_key};
print Dumper $attribs;
}
output
$VAR1 = [
'Code',
'Description',
'vsrv_id',
'vsrv_name',
'vsrv_vcpu_no',

'vsrv_mgmt_ip',

I am using the query function in cake PHP ($this->query(select...)), and I know it returns an array of the values. If the query will only return one value, what is the position of that value in the array?
Would $element = $arrayName(0) be correct?
I'm trying to use it as such:
$flowsheet_name = $this->query("select FLOWSHEET_NAME from FLOWSHEET_TEMPLATE where FLOWSHEET_ID = ".$value.";");
$flowsheet_question = $flowsheet_name(0);
array_push($this->$filedMethodMappings, $flowsheet_question => array(
CaBase::KEY_MAPPING_LOGIC_COMPLEXITY => CaBase::LEVEL3_COMPLEXITY,
CaBase::KEY_FIELD_LOGIC_NAME => 'wsUnifiedKey',
CaBase::KEY_FIELD_QUESTION_ID => ''.$value,
)
);
But I can't tell if it's working. I'm getting a double arrow error here:
$flowsheet_question => array(
In CakePHP, easy way to see what is going on in your array is:
debug($flowsheet_name);
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.
HTH,
