Delete File And File Record In Update View

Hi there,

I have a file upload which can be updated in the update view, but at the moment there’s no facility to simply delete the file. What’s the best way to do this?

Thanks in advance!

I would do this:

  • display an uploaded image

  • somewhere near display a link ‘remove’ that will hide the image and set a hidden field’s value to something

  • next to it display a file upload control

  • if there is no new file uploaded and the hidden field was set, remove the image, otherwise replace it or do nothing

This could be simplified by just using a checkbox like ‘remove this image’.

OK cool thanks, I’ll give that a try.

OK Noob question: How do I get the POST data from the checkbox in actionUpdate()?

$model->attributes->checkboxName doesn’t seem to work

Show us the view fragment that renders the checkbox and code that tries to read it.

Ah, OK I don’t think I’m rendering the checkbox correctly.

OK, so I got it working like this:

Added a checkbox to _form.php

<div class="row">

<?php echo $form->labelEx($model,'myFile'); ?>

<!--if it exists, display the current myFile file name-->

<?php if($model->myFile) {

	echo 'Current myFile file:' . $model->myFile;


<br />

<?php echo $form->fileField($model,'myFile'); ?>

<?php echo $form->error($model,'myFile'); ?>

<!--if myFile exists, display the delete myFile checkbox-->

<?php if($model->myFile) {

    echo $form->checkBox($model,'myFile'); 

} ?>


Then added this to the controller actionUpdate():

//delete old myFile file if the checkbox is checked in the update view

if($model->attributes->myFile !== 1) {

    $model->myFile = '';

    //file delete code goes here


OK forget that answer! It works but not for the reasons I want it to.

Can anyone give me a better solution please?

Replaced controller actionUpdate() code with this for more intuitive solution:

//delete old myFile file if the checkbox is checked in the update view

if($_POST['MyModel']['myFile'] == 1) {

     $model->myFile = '';


Anyone got any better solutions? I’m guessing this is functionality that people have to add on pretty much every project.
