Question

I am trying to create a search bar for website which searches the database but I find that the code it self is displaying inside the search box

<form method="get" action="chalo_search.php">
            <input type="search" name="k" size = "20" placeholder="Enter college name" value = "<?php echo $_GET['k'];?>" autofocus/>
            <input type= "submit" value="Search"/>
        </form>

is there any error in this

Answer 1

You’re echoing $_GET[‘k’] into the input box. If $_GET[‘k’] isn’t defined, you will get this error:

Notice: Undefined index: k in
… yourscript.php on line 2

(That’s what’s appearing in your search box)

Check that $_GET[‘k’] is defined first:

<?php if(isset($_GET['k'])){echo $_GET['k'];}?>
