File exceeds the defined ini size when using iframe - php

Question

I am using fancy box iframe to display my page which has the file upload button. when i click form submit i got the "File exceeds the defined ini size". i checked some of links under google and stackoverflow. But not able to find. I have enctype="multipart/form-data" in my form. Following is my code
public function createForm($data = array())
{
$this->setMethod(Zend_Form::METHOD_POST);
$this->setEncType(Zend_Form::ENCTYPE_MULTIPART);
$this->setAttrib('id', 'createsub');
$this->setAction(
$this->getView()->getHelper('url')->url(array(
'controller' => 'test',
'action' => 'create'
))
);
$this->setDecorators(array(
'Description',
'FormElements',
'Form'
));
$fnameNotEmpty = new Zend_Validate_NotEmpty();
$fnameNotEmpty->setMessage('Name cannot be empty.');
$fnameStrlen = new Zend_Validate_StringLength(1, 20);
$name = new Zend_Form_Element_Text('name', array(
'label' => 'Name:',
'value' => '',
'class' => 'text-size text',
'tabindex' => '1',
'required' => true,
'validators' => array(
array($fnameNotEmpty, true),
array($fnameStrlen, true)
),
'decorators' => $this->requiredElementDecorators,
'description' => '<img src="../../'.$baseurl.'/images/star.png" alt="required" />',
'filters' => array('StringTrim')
));
$this->addElement($name);
.... ..... .....
$brochure = new Zend_Form_Element_File('brochure', array(
'label' => 'Brochure:*',
'value' => '',
'class' => 'text-size text',
'tabindex' => '3',
'required' => true,
'filters' => array('StringTrim')
));
$this->addElement($brochure);
$submit = $this->createElement('button','addtbtn',array('class'=>'Test','label'=>'Create'));
$submit->setIgnore(true);
$this->addElement($submit);
return $this;
}
Also if i did not use iframe, I can able to upload my image...Very Strange.
I make the validation using Ajax by following code ,
<script type="text/javascript">
var Path="<?php echo $this->eurl; ?>"
$(function()
{
vReg=0
$("#addtbtn").click(function()
{
if(vReg == 1)
{
return true;
}
else{
var url = 'validateform';
var data = {};
$("input").each(function()
{
data[$(this).attr('name')] = $(this).val();
});
$("select").each(function()
{
data[$(this).attr('name')] = $(this).val();
});
$("textarea").each(function()
{
data[$(this).attr('name')] = $(this).val();
});
$.post(url,data,function(resp)
{
vError=""
for(id in resp){
oResp=resp[id];
for(key in oResp){
vError +=oResp[key]+"\n"
}
}
if(vError == ''){
vReg=1
$("#createform").attr('target','_top');
$("#createform").submit();
return true;
}
else{
$("#createform").attr('target','_self');
alert(vError)
return false;
}
},'json');
}
});
});
</script>
Also Has the following function in my controller
public function validateformAction()
{
$this->_helper->viewRenderer->setNoRender();
$this->_helper->getHelper('layout')->disableLayout();
$p = new Admin_Model_DbTable_Test();
$p = $p->getData();
foreach($p AS $k => $v)
{
$p[$v['catid']] = $v['name'];
}
$form = new Admin_Model_Form_SubTest();
$f = $form->createForm(array('parents' => $p));
$f->isValid($this->_getAllParams());
$json = $f->getMessages();
echo Zend_Json::encode($json);
}
So this will call the function which i gave on the top of the post and do the validation and return the error.But here i always getting "File exceeds the defined ini size " What I done wrong this code.
Kindly help me on this.

Answer 1

Check the upload_max_filesize setting in your .ini file(s). That's where this error comes from.

Answer 2

When you call .val() on your file input, you get the path of the file you have selected, while your validator will be expecting the file itself, hence the strange error. Most people opt to skip file inputs when doing ajax validation, and just check it on submit.
