[javascript] Double quotes within php script echo

I have a line of php code that looks like this:

echo "<script>$('#edit_errors').html('<h3><em>Please Correct Errors Before Proceeding</em></h3>')</script>";

I would like to know how to add a font color to the text correctly. If I do this:

echo "<script>$('#edit_errors').html('<h3><em><font color="red">Please Correct Errors Before Proceeding</font></em></h3>')</script>";

The word "red" is in black text and the compiler throws an error.

If I use single quotes around red, then the text does not show up at all.

Any help would be great. Thanks

You can just forgo the quotes for alphanumeric attributes:

echo "<font color=red> XHTML is not a thing anymore. </font>";
echo "<div class=editorial-note> There, I said it. </div>";

Is perfectly valid in HTML, and though still shunned, absolutely en vogue since HTML5.

CAVEATS

• It's only valid for mostly alphanumeric and dash combinations.
• Never ever do this with user input appended to attributes (those need quoting and htmlspecialchars or some whitelisting).
• See also: When the attribute value can remain unquoted in HTML5
• In other news: <font> specifically is somewhat outdated however.

Just escape your quotes:

echo "<script>$('#edit_errors').html('<h3><em><font color=\"red\">Please Correct Errors Before Proceeding</font></em></h3>')</script>";

if you need to access your variables for an echo statement within your quotes put your variable inside curly brackets

echo "i need to open my lock with its: {$array['key']}";

You need to escape the quotes in the string by adding a backslash \ before ".

Like:

"<font color=\"red\">"

use a HEREDOC, which eliminates any need to swap quote types and/or escape them:

echo <<<EOL
<script>$('#edit_errors').html('<h3><em><font color="red">Please Correct Errors Before Proceeding</font></em></h3>')</script>
EOL;
