Can't upload multiple files - php

Question

I can't seem to be able to upload several files on the same form, when not all are chosen (if I upload all, it works).
The relevant code:
<form id = "form" name = "form" action="<?php echo URLgenerator::getURL('project', 'group-edit', array('id' => $projectGroup->getId()), 'admin'); ?>" method="post" enctype='multipart/form-data'>
<?php
foreach($langs as $lang):
$langId = $lang->getId();
$displayName = $lang->getDisplayName();
?>
<fieldset id="In<?php echo $displayName; ?>">
<legend id ="<?php echo $langId?>">
<?php echo $displayName; ?>:
</legend>
<label for="name-<?php echo $langId; ?>">Name: </label>
<input type="text" id="name-<?php echo $langId; ?>" name="name-<?php echo $langId; ?>" style="width: 500px;" value="<?php echo $projectGroup->getName($lang); ?>" />
<br />
<label for="imageOff-<?php echo $langId; ?>">Image Off: </label>
<input type="file" id="imageOff-<?php echo $langId; ?>" name="imageOff-<?php echo $langId; ?>" />
<img src="<?php echo $projectGroup->getImageOffURL($lang); ?>" />
<br />
<label for="imageOn-<?php echo $langId; ?>">Image On: </label>
<input type="file" id="imageOn-<?php echo $langId; ?>" name="imageOn-<?php echo $langId; ?>" />
<img src="<?php echo $projectGroup->getImageOnURL($lang); ?>" />
</fieldset>
<?php
endforeach;
?>
<div align="center">
<input type="submit" value="Edit" id="button1" />
<input type="reset" id="button2" />
</div>
</form>
and the action (the var_dump is for debugging)
public function groupEditAction()
{
$id = $this->getRequest()->getParam('id');
$projectGroup = new ProjectGroup($id);
$name = Array();
$langs = LangFuncs::getAllLangs();
foreach($langs as $lang) {
$langId = $lang->getId();
$name[$langId] = $this->getRequest()->getParam("name-$langId");
}
$projectGroup->edit(null, $name);
$upload = new Zend_File_Transfer_Adapter_Http();
$upload->setDestination(URLgenerator::getTempFolder());
$upload->receive();
$info = $upload->getFileInfo();
var_dump($info);
return;
foreach($langs as $lang) {
$langId = $lang->getId();
try {
if($info["imageOff-$langId"]['tmp_name'] != '') {
$projectGroup->uploadImageOff($lang, $info["imageOff-$langId"]['tmp_name']);
unlink($info["imageOff-$langId"]['tmp_name']);
}
if($info["imageOn-$langId"]['tmp_name'] != '') {
$projectGroup->uploadImageOn($lang, $info["imageOn-$langId"]['tmp_name']);
unlink($info["imageOn-$langId"]['tmp_name']);
}
}
catch (Zend_File_Transfer_Exception $e) {
$this->_helper->redirector('image-upload', 'error', 'admin', array());
}
}
$this->_helper->redirector('index', 'project', 'admin', array());
}

Answer 1

The name of all the file fields is identical. Add a [] after it, i.e.
name="imageOff-<?php echo $langId; ?>[]"
Since all three have the same name, the last (empty) one overwrites the first ones.
