How to put php variable inside php variable with a javascript value

Question

I need to put php variable inside php variable with javascript value, here is some of my codes that I tried but doesnt work (its file is in .php):

$rowEmail = "EmailTest";

$script = "<script type='text/javascript'>$('#reminderModal').modal('toggle'); console.log('"echo $rowEmail;"');</script>";

$script = "<script type='text/javascript'>$('#reminderModal').modal('toggle'); console.log('".echo $rowEmail."');</script>";

$script = "<script type='text/javascript'>$('#reminderModal').modal('toggle'); console.log('".$rowEmail."');</script>";

<script> var email = <?=$rowEmail?>; console.log(email) </script> — MK12

This is vulnerable to JS and HTML injections (at least). Use json_encode to output literals that are safe to use in JavaScript context. — Peter

You have some misunderstanding on how to output data via PHP. Need something like:

$rowEmail = "EmailTest";

$script = "<script type='text/javascript'>console.log('". $rowEmail ."');</script>";
echo $script;

$script = "<script type='text/javascript'>$('#reminderModal').modal('toggle'); console.log('" . $rowEmail . "');</script>";

You don't need the echos, just concatanate the string.

If it is not a must for the love of what's good in this world do not store tags in variables like that. Makes it incredibly hard to read and debug later on.

Isn't that the 3rd thing he did?

Angel Deykov Over a year ago

yes, but he didn't output(echo) the string afterwards, so nothing happened ...

It is and it works just fine. Provided he included the jQuery library properly.

Your last line is correct I don't know you why say it doesn't work, I've tried it and it works :

<?php
$rowEmail = "EmailTest";
$script = "<script type='text/javascript'>$('#reminderModal').modal('toggle'); console.log('".$rowEmail."');</script>";

echo $script;
// displays <script type='text/javascript'>$('#reminderModal').modal('toggle'); console.log('EmailTest');</script>

Didn't work, because $script was not echoed afterwards ...
