putting a php variable in a HTML form value

I've got a php variable like so.. $name = $_REQUEST['name']; I'd like to put it in a HTML form field's value e.g in here..开发者_JS百科 <input type="text" name="name" value=(php variable here) /> How would I do so?

Thanks.

value="<?php echo htmlspecialchars($name); ?>"

You can do it like this,

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

But seen as you've taken it straight from user input, you want to sanitize it first so that nothing nasty is put into the output of your page.

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