Hi,
I'm trying to trigger my JS function to be executed after successful form post in order to update some arbitrary container on page with the data.
I saw that there is "updaters" array in JSON response but I'm not sure how to fill it with data. Should I do that in the form definition array, or somewhere else. Do I maybe take wrong approach to this? I feel like I'm missing something :)
Is there maybe a link to detailed tutorial on using Ajax.module where I could get into more details?
Thanks for help,
Ivan

You can pass custom
You can pass custom information to javascript via hook_submit of your ajax form.
In your module:
function mymodule_myform_submit(&$form, &$form_state) {// submission code
$form['#ajax']['some_data'] = 'some_value';
}
In your javascript plugin:
Drupal.Ajax.plugins.mymodule = function(hook, args) {if (hook === 'message') {
alert(args.data.options.some_data);
}
}
I'm not sure if this is the right way, but it worked for me.
Sorry about asking a
Sorry about asking a somewhat different question. But what is the // submission code?
I want to create a custom message on post success.
<?phpDrupal.Ajax.plugins.mymodule = function(hook, args) {
if (hook === 'message') {
alert('post success!');
}
}
?>
I just need to know what the submission code should be.
Thanks!
"// submission code" is your
"// submission code" is your PHP code, which is executed when your form is submitted (i.e. form data saved to a database). Simply add
$form['#ajax']['form_submitted'] = 1;at the end of your form submit function (I assume that you are writing your own module).
You wrote:
<?phpDrupal.Ajax.plugins.mymodule = function(hook, args) {
if (hook === 'message') {
alert('post success!');
}
}
?>
This function should be written a javascript, not in PHP. Your module should include this file in hook_preprocess_page (see plugins\thickbox dir of the ajax module to see how it is done).
Your javascript file should look like this:
Drupal.Ajax.plugins.mymodule = function(hook, args) {if (hook === 'message' && args.data.options.form_submitted!=undefined) {
alert('post success!');
}
Thanks a lot! It worked when
Thanks a lot!
It worked when I had:
if (hook === 'message') {
in the js, but not when it was:
if (hook === 'message' && args.data.options.form_submitted!=undefined) {
Do you know why that is?
Thanks!
Edit: Do you also know how to return something if the saving fails? And how to change the loading... text to saving... ?
Thanks!
I guess the best way is to
I guess the best way is to define all variables passed to javascript in the form constructor function (myform_form).
$form['#ajax'] = array('enabled' => TRUE,
'form_submitted' => '',
'another_variable' => 'default_value',
);
If the saving fails (i.e. in myform_validate) then set a variable in a validate function:
if ($error_detected) {form_set_error(...);
$form['#ajax']['form_submitted'] = 'no';
}
Set the variable in a similar way in your submit function (i.e. $form['#ajax']['form_submitted'] = 'yes' at the end of the function).
Then, your javascript should check for:
if (hook === 'message' && args.data.options.form_submitted==='yes') { alert('success'); }else { alert('validation failed'); }
Debug your javascript with firebug if neccessary.
Module Needed
Note that the "AJAX" http://drupal.org/project/ajax) module is required for "pgorecki"'s solution above to work.
Values stored in args.data.options not updating
Hi. I've been trying to update some values on a page after submission via the Ajax.module as described above. Using the snippets above as a reference, the value I am setting for 'form_submitted' in my module's validate function is not being updated on the page ( it's value remains a blank String). I'm using firebug to debug and watch the values on the page after returning and nothing has changed. Any help/thoughts are appreciated.
You must set notfunction
You must set not
function mymodule_myform_submit($form, &$form_state) {}but
function mymodule_myform_submit(&$form, &$form_state) {}To force this method work.
And 1 more:
Don't know why but for me this works only this way
if (hook === 'message' && args.options.form_submitted==='yes') { }not
if (hook === 'message' && args.data.options.form_submitted==='yes') { }drupal 6
In my JavaScript I did this
In my JavaScript I did this instead of writing it in the module. All I wanted is to reset the form and I came across this other variable 'status' in the response loaded already. If the form has errors, it returns false, otherwise it returns true. Hope it helps someone.
Drupal.Ajax.plugins.contactformplus = function(hook, args) {
if (hook === 'message' && args.data.status=== true) {
$("form.ajax-form").each(function() {
$(this).get(0).reset();
});
}
}
