I am trying to get the data from the form I created where I used an array to name them like:
<input type="text" name="fname[]" />
<input type="text" name="mname[]" />
<input type="text" name="lname[]" />
where the said form field are dynamically inserted or removed in the page.
On my script to get the values of the forms, I wrote something like:
$student = array(
'fname' => '$_POST[fname]',
'mname' => '$_POST[mname]',
'lname' => '$_POST[lname]',
);
But when I used var_dump to see the values, each field will be indexed from zero and if it has repeating fields, it would be again be declared as another array inside an array.
What I wanted to do is to have an array with this stucture:
$student = array(
array(
'fname' => 'fname1',
'mname' => 'mname1',
'lname' => 'lname1'
),
array(
'fname' => 'fname2',
'mname' => 'mname3',
'lname' => 'lname2'
)
);
I tried using a loop but I just fail again and again. Can anyone help me solve this problem?
Thank you in advance for your help.
<input type="text" name="student[]['fname']" />
<input type="text" name="student[]['mname']" />
<input type="text" name="student[]['lname']" />
no loops necessary. Your $_POST['student'] variable will automatically be the array you wanted to achieve.
EDIT: this isn't achieving the desired result. It's incrementing student for each field. adding an n value to the first set of brackets like student[n][fname] does achieve the desired result. I don't know how the script is written to dynamically generate these three fields on the fly, but if you can figure out how to add an n value you're golden.
<?php
for($i=0; $i<count($_POST['fname']); $i++) {
$student[] = array(
'fname' => $_POST['fname'][$i],
'mname' => $_POST['mname'][$i],
'lname' => $_POST['lname'][$i],
);
}
?>
Oops, I thought Stephan's answer would suffice, but rather, it should be the following I believe (can't test right now). Try it:
<input type="text" name="student[0]['fname']" />
<input type="text" name="student[0]['mname']" />
<input type="text" name="student[0]['lname']" />
<input type="text" name="student[1]['fname']" />
<input type="text" name="student[1]['mname']" />
<input type="text" name="student[1]['lname']" />
etc...
(note the added numeric indexes)
Then when you do a echo '<pre>' . print_r( $_POST[ 'student' ], true ); you should see the structure you are looking for.

I'm building a custom settings form in Drupal 7, with an image upload field. This image field should allow multiple uploads.
After some research I found out you can do this with managed_file and '#attributes' => array('multiple' => 'multiple'). However this doesn't seem to do anything.
This is the code I currently have:
$form['frontpage_banner_images'] = array(
'#type' => 'managed_file',
'#title' => t('Frontpage Images'),
'#name' => 'files[]',
'#attributes' => array(
'multiple' => 'multiple',
'class' => 'testclass',
),
'#upload_location' => 'public://homepage-banners/',
'#default_value' => variable_get('frontpage_banner_images'),
);
With this as result:
<div class="form-item form-type-managed-file form-item-files-">
<label for="edit-frontpage-banner-images-upload">Frontpage Images</label>
<div id="edit-frontpage-banner-images-upload" class="testclass form-managed-file">
<input type="file" id="edit-frontpage-banner-images-upload" name="files[frontpage_banner_images]" size="22" class="form-file">
<input type="submit" id="edit-frontpage-banner-images-upload-button" name="frontpage_banner_images_upload_button" value="Upload" class="form-submit ajax-processed">
<input type="hidden" name="frontpage_banner_images[fid]" value="0">
</div>
</div>
As you can see, the testclass from my #attributes is being applied on the wrapping div and not on the file input. So the multiple attribute isn't doing anything.
This is what I'm trying to achieve (Photoshopped):
Any help on how to achieve this is appreciated.
The multiple option does not seem to be supported. Then again you are using it under the #attributes. This would cause IMO the html element to have an atttribute multiple, but I don't see anything in /modules/file/file.js to pick up on that, so that's presumably why it's not doing anything.
You're probably better off using plupload, as suggested here.
I have created below fields in my form-
<input type="text" id="ProductPrice1" class="small" name="data[Product][price][1]">
<input type="text" id="ProductPrice1" class="small" name="data[Product][price][2]">
<input type="text" id="ProductPrice1" class="small" name="data[Product][price][3]">
<input type="text" id="ProductPrice1" class="small" name="data[Product][price][4]">
Now I am trying to add validation for above fields by using below model function-
public function productValidates() {
$validate= array();
$validate = array(
'name'=> array(
'mustNotEmpty'=>array(
'rule' => 'notEmpty',
'message'=> __('PRODUCTS.TITLE_BLANK_ERROR',true)
)
),
'description'=> array(
'mustNotEmpty'=>array(
'rule' => 'notEmpty',
'message'=> __('PRODUCTS.DESCRIPTION_BLANK_ERROR',true)
)
),
'category_id'=> array(
'mustNotEmpty'=>array(
'rule' => 'notEmpty',
'message'=> __('PRODUCTS.SELECT_CATEGORY_ERROR',true)
)
),
);
$count = $this->data[$this->name]['total_prices'];
for($i=1; $i<= $count;$i++){
$validate['price'][$i] = array(
'1' => array(
'rule' => array('notEmpty',true),
'message' => __('PRODUCTS.PRICE_EMPTY_ERROR',true),
'last' => true
)
);
}
$this->validate = $validate;
return $this->validates();
}
But its not working.
Can you please suggest what’s the issue here?
I suppose that you are using cakephp 2.X
I think that the problem is the loop, instead of that add a custom validation method to check that the prices are not empty.
Here is the link to the book with an example.
http://book.cakephp.org/2.0/en/models/data-validation.html#adding-your-own-validation-methods
Another solution is to make a table Prices with columns id|product_id|value, put the association in the Models, put the validation criteria of the prices into the Price Model and in the ProductController put "saveAll" instead of save.
In this case your form must be like:
<input type="text" id="ProductName" class="small" name="data[Product][name]">
<input type="text" id="ProductDescription" class="small" name="data[Product][description]">
<input type="text" id="PriceValue1" class="small" name="data[Price][0][value]">
<input type="text" id="PriceValue1" class="small" name="data[Price][1][value]">
<input type="text" id="PriceValue1" class="small" name="data[Price][2][value]">
<input type="text" id="PriceValue1" class="small" name="data[Price][3][value]">
if this does not answer your question I will need more data such as the controller and the structure of your db
I have a column in my table named 'availability_option' with type enum('0', '1', '2'). Zero means 'Fixed Price', One means 'Auction', Two means 'Both'.
I want to generate 2 checkboxes dynamically One for Fixed Price and another 'Auction'.
How is it possible?
I didi it static.
But it should not be the right syntax of yii.
<input value="0" id="fixedprice" type="checkbox" name="ProductShop[availability_option][]">
<label for="fixedprice">Fixed Price</label>
<input value="1" id="auctionprice" type="checkbox" name="ProductShop[availability_option][]">
<label for="auctionprice">Auction</label>
I want it dynamically, So how is it possible?Any idea?
Use checkboxList():
<?= $form->field($model, 'attribute_name')->inline(true)->checkboxList([0 => 'Fixed Price', 1 => 'Auction']) ?>
http://www.yiiframework.com/doc-2.0/yii-bootstrap-activefield.html#inline%28%29-detail
I was facing The same problem and I solved It by doing like this :
<?php echo $form->field($model, 'name[]')->checkboxList(['a' => 'Item A', 'b' => 'Item B', 'c' => 'Item C']); ?>
Note that the checkboxList expects the first argument of the passed array to be of string type as well so you may need to make changes to your array.
Generated HTML will be as:
<label><input type="checkbox" name="fomrmName[name][]" value="'1'"> a</label>
another way by which I solved My problem was to wrap the checkbox in foreach block like following:
<?php foreach($vendorsData as $value){?>
<li><?= $form->field($ucVendors, 'vendor_id['.$value.']')->checkbox(array('label'=>$value)); ?>
and the Generated html is as:
<label><input type="checkbox" id="usedcarvendors-vendor_id-value" name="UsedCarVendors[vendor_id][value]" value="1"> value</label>

CakePHP usually place labels before the input, so doing this:
echo $this->Form->input('subject');
We obtain this:
<div class="input text required">
<label for="TicketSubject">Subject</label>
<input name="data[Ticket][subject]" maxlength="255" type="text" id="TicketSubject">
</div>
Is there any way to place the label after the input to obtain this?
<div class="input text required">
<input name="data[Ticket][subject]" maxlength="255" type="text" id="TicketSubject">
<label for="TicketSubject">Subject</label>
</div>
Thanks.
The proper way is using the the 'format' option.
$this->Form->input('subject', array(
'format' => array('before', 'input', 'between', 'label', 'after', 'error')
));
Didn't anyone read the API :)
You can try this:
echo $this->Form->input('subject', array('label' => false, 'after' => $this->Form->label('Subject:')));
You can do like this also -
echo $this->Form->input('subject', array('label' => false, 'after' => '<label for="subject">Subject</label>'));
i am trying to create a Radio button using Cakephp like the one the result should resemble like
<div data-attr="radio" id="1">
<label id="label1">Untitled1</label><br/>
<input type="radio" value="option1" id="Radio11" name="Workexperience"/>
<label for="Radio11">Option1</label>
<input type="radio" value="option2" id="Radio12" name="Workexperience"/>
<label for="Radio12">Option2</label>
</div>
how to generate so using Form helper..
Please suggest me..
This might help,
http://book.cakephp.org/view/189/Automagic-Form-Elements#options-before-options-between-options-separator-a-191
For radio type input the 'separator' attribute can be used to inject markup to separate each input/label pair.
Code View
<?php echo $form->input('field', array(
'before' => '--before--',
'after' => '--after--',
'between' => '--between---',
'separator' => '--separator--',
'options' => array('1', '2'),
'type' => 'radio'
));?>
Output:
<div class="input">
--before--
<input name="data[User][field]" type="radio" value="1" id="UserField1" />
<label for="UserField1">1</label>
--separator--
<input name="data[User][field]" type="radio" value="2" id="UserField2" />
<label for="UserField2">2</label>
--between---
--after--
</div>
Looks like $form->radio() should do what you need. I don't know if it will look exactly like your example.
