Dynamic form fields and multiple inputs

Yii 1.1 General Discussion

Hi there,

First of all, first post =D Thanks for the yii framework, works great. And, sorry for my English, as I am a French Canadian.

I’m currently building a web application that will allow people to buy and sell their stuff. In order for them to sell, they have to fill a form which is 4 fields

  • The name

  • The description

  • The category

  • A checkbox, true meaning they’re selling. Otherwise, they buy

Since people may have more than 1 item to sell at once, I placed some jQuery in it in order to duplicate these fields. I am using latest jQuery release with a plugin that is called "relCopy". It can be found there: http://www.9lessons.info/2010/04/jquery-duplicate-field-form-submit-with.html

But when I make a var_dump of my post variable, I receive only the last item that has been entered…I double checked what I was usually doing in PHP (without yii) and everything seems fine:

on my _form.php, my items go as follow (only an example)


 <?php echo $form->textField($model,'ITE_Name[]',array('size'=>80,'maxlength'=>45)); ?>

However, I’ve noticed that it’s written on the source code


 <input size="80" maxlength="45" name="Item[ITE_Name]" id="Item_ITE_Name" type="text" value="" />

Why are the brackets missing at the end ? I think this is why, when I receive the form there’s only the last insert.

So I’m wondering. Shall I use standard html forms for this one, or is there an implemented method that works great in Yii ? I searched on google but the keywords are too common and generate alot of trash results.

Thanks for your replies!

You have to collect tabular input, there is a page in the definitive guide to Yii.

You have to generate the feld like that:




<?php echo $form->textField($model,'[$i]ITE_Name',array('size'=>80,'maxlength'=>45)); ?>

Where $i is an index (count from 1 to the number of your elements in page). Like that the input field will be:




 <input size="80" maxlength="45" name="Item[0][ITE_Name]" id="Item_0_ITE_Name" type="text" value="" />

And you will have receive:




$_POST=array(

     Item=>array(

          0=>array(

               ITE_Name=>value

          )

     )

)

Read the manual about it.

Thank you. I didn’t know it is named “tabular input”.

With some tweaks, it definitely works!

Thanks again
