Double quotes in HTML form (PHP)

Question

I have the following code:

<input type="text" name="firstName" id="firstName" value=" <?php setValue( "firstName" ) ?> " />

The problem is, the value attribute reaches the first quote <?php setValue( as a value of the input field. How to deal with it?

I think the code is right and should work. However you can use `'` instead. — Mohammad, Oct 16 '16 at 12:54
Given the answers below, are you sure you're running this as `.php` and inside a PHP environment such as `http://localhost` and not as `file:///` and/or an `.html` file? I hope you're going to reply to comments here and not just answers. — Funk Forty Niner, Oct 16 '16 at 14:26
what does this function do? `setValue()`. Plus, is that JS or PHP? — Funk Forty Niner, Oct 16 '16 at 14:31
`function setValue($fieldName){ if( isset( $_POST([$fieldName]))){ echo $_POST([$fieldName]); } }` — Ofelia Muradova, Oct 16 '16 at 14:37
@Fred-ii- you're right, i did! I did it with `file:///` ... well, now it's showing an error on the function `setValue`: "Cannot use isset() on the result of a function call" — Ofelia Muradova, Oct 16 '16 at 14:39

Try concat :

<input type="text" value="' . <?php setValue('firstName') ?> . '"/>

You could use an echo this way

<?php echo  '<input type="text" name="firstName" id="firstName" value="'.  
                 setValue( "firstName" ). '" />' ; ?>

@ShiroiOkami what's mean don't work .. you have an error .?. or the value is not the string "firstname" ? – ScaisEdge Oct 16 '16 at 13:18

@scaisEdge See my comments under the question; that's what I think is happening here. – Funk Forty Niner Oct 16 '16 at 14:30
@scaisEdge [And I was right...](http://stackoverflow.com/questions/40070442/double-quotes-in-html-form-php#comment67416345_40070442) being *"you're right, i did! I did it with file:///"*. So I closed the question. – Funk Forty Niner Oct 16 '16 at 14:40

I think your data is return firstName value or whatever by function setValue. You have to echo your value that is

<input type="text" name="firstName" id="firstName" value=" <?php echo setValue( "firstName" ) ?> " />

and your code is correct. Than use

<?php echo  '<input type="text" name="firstName" id="firstName" value="'.  
             setValue( "firstName" ). '" />';  ?>

@ShiroiOkami Sorry, I did not understand – Kumar Oct 16 '16 at 13:13
it displays the field and the value inside is ` – Ofelia Muradova Oct 16 '16 at 13:27
@ShiroiOkami check again I have changed it. – Kumar Oct 16 '16 at 13:33
I've checked and now it prints only last characters `'; ?>` – Ofelia Muradova Oct 16 '16 at 14:17

did you have php, means jsfiddle.net only support javascript, html and css. – Kumar Oct 16 '16 at 14:35
