Drupal: Form Validation Messages Order

27 July 2017, in

Hello all Drupalists,

Have you ever had a problem with form validation messages order, ... I think we all had this issue.

For some reason validation messages are not ordered the right way (with the same order as the form fields).

For this reason, I wrote the below code to be used to reorder form validation messages.

Note that the below code also has a function to be used if you are using conditional fields module to manage field dependencies.

Drush command terminated abnormally due to an unrecoverable error

28 October 2016, in

This error might be very frustrating to you, specially when you can't see any issue with your code, can't check error log, and obviously can't do drush watchdog-show. After some search and investigation, found that I had a call to drupal_goto() in an implementation for hook_init() which is implemented on every bootstrap process. The solution was to add a condition to check before doing the drupal_goto() to check that the source is not from drush:

Drupal: Custom node edit menu callback, image upload widget disappears when change file

21 March 2016, in

I had an issue with a custom node edit menu callback, that when the remove button is clicked to replace the current uploaded image, the whole widget disappears.

I already loaded node.pages.inc file as follows:

module_load_include('inc', 'node', 'node.pages');

BUT, apparently you should add these line to the menu item array:

Drupal7 Views3: Empty "Row style output" templates

20 May 2015, in

I had an issue when I was trying to create a new display and tried to theme it, I found the "Row style output" template suggestions like the following and with no template content:

 

Row style output: .tpl.php, --display.tpl.php, --type.tpl.php, ...

 

After some investigation, I found that the reason that caused this that my display "Format" shows "Content" not "Fields", so it shows rendered content and can not have row style templates.

Drupal file_copy won't work outside of the Drupal installation directory

9 January 2012, in

The selected file could not be uploaded, because the destination is not properly configured

This "feature" has bitten me before. It's one of those annoying Drupal things which would be fine if the error message wasn't so misleading.

What's happening is that file_copy() calls file_create_path()

<?php
function file_copy(&$source, $dest = 0, $replace = FILE_EXISTS_RENAME) {
$dest = file_create_path($dest);
?>
