Variable data in text boxes

[Space Cowboy]

PHP Code:

// Display name field an error if needed
   echo '<tr><td><label>Enter Student Number or Username<br /> 
    <input name="uid" type="text" id="uid" value="$name2" /></td></tr>'; 


I want the above text box value to be linked to the variable $name2 that can change.

Thanks Trev

I'm not overly familiar with PHP, but I think you have to enclose variables in curly braces if you want to include them as part of a string.
Something like this:

PHP Code:

<?php

echo '<tr><td><label>Enter Student Number or Username<br />  
    <input name="uid" type="text" id="uid" value="{$name2}" /></td></tr>';

?>

<input name="uid" type="text" id="uid" value="<?=$name2?>" />

The above in bold will work for PHP although I have been critized in the past that this is "messy" I've never seen Tamlins suggestion in a manual i'd be interested to know if that works for you!

I think I read it here: PHP: Strings - Manual

oh sorry i read the originally post wrong i saw the table and thought he was wanting the variable in html don't know why I ignored the echo. I decided to test this here http://www.goolefitc.co.uk/test_brackets.php and it works great good tip Tamlin.

Alternative method below (think i may be switching to squiggly brackets tho!)

echo '<tr><td><label>Enter Student Number or Username<br />
<input name="uid" type="text" id="uid" value="'.$name2.'" /></td></tr>';

PHP Code:

// Display name field an error if needed 
   echo '<tr><td><label>Enter Student Number or Username<br />  
    <input name="uid" type="text" id="uid" value="'.$name2.'" /></td></tr>'; 


PHP will read variables if you use double quotes. if you use single quotes you must escape then concatenate the string as above. If you want to avoid the concatenation you could use the code below. Note the difference in quote marks.

PHP Code:

// Display name field an error if needed 
   echo "<tr><td><label>Enter Student Number or Username<br />  
    <input name='uid' type='text' id='uid' value='$name2' /></td></tr>";
