Can I have a php if statement inside a jquery script in Drupal 7?

Question

I have a jquery script that loads on document ready and I want to display a hidden popup if a user has already clicked a button (button field). But the condition I check is with php code.

<script>
$( document ).ready(function() {
  if (<?php $user_fields->field_button['und'][0]['value'] = 1 ?>) {
    var popup = document.getElementById("testpopup1").style.visibility = "visible";
    alert("x");
  }
});
</script>

But this way doesn't work. Is there a way to put the php code inside the if statement of my jquery code or I have to try something else?

You don't need Javascript to do an if and all.

In your HTML

<?php if ($user_fields->field_button['und'][0]['value'] === 1) { ?>

    <div id="testpopup1">Your content</div>

    <script>alert('x');</script>

<?php } ?>

And the onload function?The php tags should be both at the start and the end of the if statement? And I have this code at the node--XX.tpl.php file

Ok, I got it! you only missed the '=1' at the if statement, but it totally worked. I mixed js and php and I messed up, but your answer worked!

$(document).ready() is unnecessary here since you don't even use jQuery inside your JavaScript. Don't forget to upvote and mark the answer as solved if it helped ;)

I can't upvote because I lack reputation but I mark it as solved!

Actually, the divs and the script load in both cases, even if the value is one and not

Save the value of the PHP value in a Javascript variable.

$(document).ready(function() {
  var undValue = <?= $user_fields->field_button['und'][0]['value'] ?>;
  if (undValue === 1) {
    document.getElementById('testpopup1').style.visiblity = 'visible';
    alert('x');
  }
});

I don't know much about php, but I think that the <?= part is wrong, right?Should I replace it with <?php instead?

Elie Faës Over a year ago

In fact, <?= is equivalent to <?php you can use both. But I would suggest you to be explicit and use <?php

@ArgirisA It's a shorthand for <?php echo. It definitely works.
