[SOLVED] Keep selected option after failed submit

[ovy79ro]

Hello,

 

I want to know how to keep selected option after submit. For example, I have the following select input:

................................................

<select name="id_supplier">

<option value="0">0</option>

<option value="1">1</option>

<option value="2">2</option>

<option value="3">3</option>

</select>

..................................................

 

If i select option 2, for example, after submit, selected value is not kept and returns to the first option, o.

 

I try the following code but it is not working.

 

................................................

<select name="id_supplier">

<option value="0" {if isset(($id_supplier) && $id_supplier==0) selected="selected"}{/if}>0</option>

<option value="1" {if isset(($id_supplier) && $id_supplier==1) selected="selected"}{/if}>1</option>

<option value="2" {if isset(($id_supplier) && $id_supplier==2) selected="selected"}{/if}>2</option>

<option value="3" {if isset(($id_supplier) && $id_supplier==3) selected="selected"}{/if}>3</option>

</select>

..................................................

 

Can someone help me?

 

Thank you!

Anyone?

How is $id_supplier being set? Are you using Tools::getValue('id_supplier')? That's what PrestaShop usually uses to make the values persist even if there's an error message.

$id_supplier get value with $_POST. I dont use Tools.

You can try setting the value on the <select> like this:

<select name="id_supplier"{if isset($id_supplier)} value="{$id_supplier|intval}"{/if}>

Solved!

Work with this:

<option value="1" '.(Tools::getValue('id_supplier') == 1 ? 'selected="selected"' : '').'>1</option>
