Using a PHP variable in a text input value = statement

Question

I retrieve three pieces of information from the database, one integer, one string, and one date.

I echo them out to verify the variables contain the data.

Answer 1

Try something like this:

<input type="text" name="idtest" value="<?php echo htmlspecialchars($name); ?>" />

That is, the same as what thirtydot suggested, except preventing XSS attacks as well.

You could also use the <?= syntax (see the note), although that might not work on all servers. (It's enabled by a configuration option.)

Answer 2

From the HTML point of view everything's been said, but to correct the PHP-side approach a little and taking thirtydot's and icktoofay's advice into account:

<?php echo '<input type="text" name="idtest" value="' . htmlspecialchars($idtest) . '">'; ?>

Answer 3

I have been doing PHP for my project, and I can say that the following code works for me. You should try it.

echo '<input type = "text" value = '.$idtest.'>'; 

Answer 4

Solution

You are missing an echo. Each time that you want to show the value of a variable to HTML you need to echo it.

<input type="text" name="idtest" value="<?php echo $idtest; ?>" >

Note: Depending on the value, your echo is the function you use to escape it like htmlspecialchars.

Answer 5

If you want to read any created function, this how we do it:

<input type="button" value="sports" onClick="window.open('<?php sports();?>', '_self');">

Answer 6

You need, for example:

<input type="text" name="idtest" value="<?php echo $idtest; ?>" />

The echo function is what actually outputs the value of the variable.
