Hello CI.
I’ve been struggling for a while with this problem.
I want to validate my form after i submitted it.
So when the field name is required and it’s empty he has to show a error for me.
Without Ajax it goes like it should. But with Ajax it’s a hell.
Here are some examples.
This is the form to submit.
<?php $this->validation->showError(); ?>
<div id="formContainer">
<?php echo form_open('aftakkasten/add',array("id"=> 'form'));?>
<input type="hidden" name="editID" value="<?php echo $hiddenID; ?>">
<fieldset class="fieldForm">
<legend>Aftakkast parameters invoeren</legend>
<?php foreach($query->result() as $row): ?>
<table id="invoerscherm" cellspacing="0">
<tr>
<td>Modbus adres</td>
<td><input type="text" name="modAdres" value="<?php echo $row->Address;?>" maxlength="3" /></td>
</tr>
<tr>
<td>Proces code</td>
<td><input type="text" name="ProcesCode" value="<?php echo $row->ProcesCode;?>" maxlength="50" /></td>
</tr>
</table>
</fieldset>
</div>
<div class="pos_button">
<input type="submit" name="submit" value="Opslaan" />
</div>
</form>
<?php endforeach; ?>
You see i got a other validation function. I’ve extended the original one.
Here’s my code:
<?php
class MY_Validation extends CI_Validation {
function MY_Validation()
{
parent::CI_Validation();
$this->ci =& get_instance();
}
function showError()
{
if($this->ci->validation->error_string){
echo '<div id="hiddenBody">';
echo '</div>';
echo '<div id="error">';
echo '<h5>Fout</h5>';
echo '<div class="errorBody">';
echo $this->ci->validation->error_string; // Wanneer een error is gecreerd word dit getoond.
echo '<div class="actionError">';
echo '<input type="button" value="Doorgaan">';
echo '</div>';
echo '</div>';
echo '</div>';
}
}
}
?>
And here is my ajax function that escape the submit and try to make it a ajax call.
$(document).ready(function() {
var options = {
target: '#content', // target element(s) to be updated with server response
method: 'post' //beforeSubmit: showRequest, // pre-submit callback
//success: showResponse // post-submit callback
};
// bind to the form's submit event
$('#form').submit(function() {
$(this).ajaxSubmit(options);
return false;
});
});
And my controller looks something like this:
$rules['modAdres'] = "required";
$this->validation->set_rules($rules);
$fields['modAdres'] = 'Modbus adres';
$this->validation->set_fields($fields);
if ($this->validation->run() == FALSE)
{
if($this->ajax->isAjax() === false)
{
$data['view'] = 'aftakkasten_view';
$data['space'] = $this->fillSpace();
$data['query'] = $this->aftakkast_model->getAftak();
$this->template->load('main',$data);
}
else{
$data['query'] = $this->aftakkast_model->getAftak();
$this->template->load('aftakkasten_view',$data);
}
}else
{
$this->save();
}
Every time i submit the page. Without the value of modAdres the form dont show a error message. Without Ajax it is working.
But customer is king, so i want this to work.
After submit my page try to reload and there’s no error message and i can’t click anymore on the submit button.
Maybe my ajax call is wrong?
Can somebody please help me with this?
Thanks
