How to pass dynamical field names to validation object?

[eluser]Skuja[/eluser]
I am making a form that has dynamicaly generated input fields. These fields are names in each language that has been created, it looks like something like this:

Code:

//$languages variable stores a query where i get data from db
<?foreach($languages->result() as $language):?>
<?$name = $language->code.'_name';?>
field name in &lt;?=$language->name?&gt; language: &lt;input type="text" name="&lt;?=$name?&gt;" &lt;?=$this-&gt;validation->$name;?&gt;><br>
&lt;?endforeach;?&gt;

ofcourse

Code:

<?=$this->validation->$name;?>

causes an error, so i'm stuck and can't figure out any way how to deal with this problem.

Here's what you need to do:

Create a variable, named "$fields" (or something like that) and then create a conditional check that either dumps your database->get() into the $fields variable, or your validation object into the $fields variable.

That way you can use the same variables in your form view.

Hopefully that makes sense. I'm just finally figuring the validation/dynamic data in forms myself.

Your question is a bit confusing.

assuming that you correctly trying to call it:

Code:

<?=$this->validation->{$name};?>

would work.

Pygon's solution worked for me too. Example:

Code:

<?php
for ($i=1; $i <= $how_many; $i++)
{
$answer = 'answer'.$i;
?&gt;
<dt><label for="answer&lt;?php echo $i; ?&gt;">Answer &lt;?php echo $i; ?&gt;</label></dt>
<dd>
&lt;input type="text" name="answer&lt;?php echo $i; ?&gt;"  value="&lt;?= $this-&gt;validation->{$answer}; ?&gt;" />
</dd>
&lt;?php  }     ?&gt;

This also works

Code:

<?= $this->validation->$answer; ?>
