Trouble writing php variables into javascript

Question

 'success'=>'js: function(data) {
        $("#addToListDialog$model->product_id").dialog().dialog("close");}'

I'm trying to write the above piece of javascript, but can't get the right combination of curly brackets a single/double quotes in order to resolve the PHP variable. How should I be writing this?

Try wrapping your PHP variable in curly braces: {$model->product_id} — andrewsi

You shouldn't be building JavaScript with PHP. It's A Bad Idea™. Keep your HTML in .html files, your CSS in .css files, and your JS in .js files. Use [data-*] attributes and classes if you need to pass data to JavaScript. — zzzzBov

why are you closing the dialog as soon as you create it. if you don't want it auto opened then just use _id').dialog({ autoOpen: false }) — SpYk3HH

A cleaner way:

'success'=>'js: function(data) {
        $("#addToListDialog'.$model->product_id.'").dialog().dialog("close");}'

I prefer this approach as it is cleared that the string contains a PHP variable. Embedding variables inside strings is easy to overlook, which makes it hard to debug. Also, when refactoring (e.g. Rename $model to $somethingElse), most IDEs will not rename the variable if it is within a string.

@thaJeztah One IDE will ... Komodo :P

and most that do have color coding so you cant miss the variables inside blocks of text. its about the escaping really ;)

@MarZab I agree, in this case it's more convenient. Here is a discussion on the subject stackoverflow.com/questions/5605965/…

@SpYk3HH Maybe should have left out 'most' LOL, my IDE does it as well, but I've had situations where an IDE didn't properly pick up the variable

Your PHP string must be in double quotations.

This should do the trick:

'success'=>"js: function(data) {
        $(\"#addToListDialog{$model->product_id}\").dialog().dialog(\"close\");}"
