Need help modifying this search.

[phpnoobie9]

The below code shows the form if it's empty. I'm trying to edit it to show an error if someone uses less than 3 characters.

I tried replacing get with: $_GET['search'] < 3

 

 

Search is from http://www.insanevisions.com/article-193-PHP-Search-Tutorials.html

Search Form

<?php 
if ($ _GET['search'] == "") { 
?> 
<form action="phpsearch.php" method="get"> 
<input type="text" name="search"><br> 
<input type="submit" value="Search"> 
</form> 
<?php 
} 
?>

Try

 

<?php 

if (isset($_GET['search'])){
   
   if (strlen($_GET['search']) < 3){
      echo "Search is less than 3 chars";
   }
}

if ($ _GET['search'] == "") { 
?> 
<form action="phpsearch.php" method="get"> 
<input type="text" name="search"><br> 
<input type="submit" value="Search"> 
</form> 
<?php 
} 
?>

It echos that and still shows the displays. If I enter the letter 'r' anything that has 'r' in it displays. I'm trying to limit it.

<?php 

if (isset($_GET['search'])){
   
   if (strlen($_GET['search']) < 3){
      echo "Search is less than 3 chars";
      exit;
   }
}

if ($ _GET['search'] == "") { 
?> 
<form action="phpsearch.php" method="get"> 
<input type="text" name="search"><br> 
<input type="submit" value="Search"> 
</form> 
<?php 
} 
?> 

 

that should make the script stop once it reaches the echo error.
