Solution provided for displaying value is giving error

<form method="get" action="./"> <input type="text" name="s" value="<?php if(isset($s)) { echo htmlspecialchars($s); } ?>"> <input type="submit" value="Go"> </form>

It is complaining that 'value' should be used but i think the above solution should work

Hi Chetan,

Your solution could work, based on what is discussed in the challenge, the answer in this case would be:

<form method="get" action="./">
    <input type="text" name="s" value="<?php if($search_term != "") echo htmlspecialchars($search_term); ?>">
    <input type="submit" value="Go">
</form>

You could also accomplish this with the ternary operator, for example:

<input type="text" name="s" value="<?php echo isset($search_term) ? $search_term : ''; ?>">

As you stated, there are other methods to accomplish this, but that would be difficult to cover all bases in a single lesson, instead the challenge is focusing on the method covered in the video.

Hope that helps!
