I am getting the below error:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'testing order by id'
Here is the main page..
echo "<div ><a href='secondpage.php?title=".urlencode($row['title'])."'>".wordwrap($row['title'], 35, "<br />\n", true)."</a></div>";
and here is the second page the error appearing on. the address bar reads http://localhost/secondpage.php?title=more+testing
<?php
$mydb = new mysqli('localhost', 'root', '', 'test');
$sql = "SELECT * FROM test where urlencode(title) =".$_GET['title']" order by id ";
$result = $mydb->query($sql);
if (!$result) {
echo $mydb->error;
}
?>
<div>
<?php
while( $row = $result->fetch_assoc() ){
echo $row['firstname'];
}
$mydb->close ();
?>
</div>
You want to use
urldecode
to decode the encoded string in your query:I'm assuming you have a column named
title
in yourtest
table. I don't think MySQL hasurlencode
function unless you have a procedure by that name which functions exactly like PHP'surlencode
.Update:
Thanks to @GeorgeLund, who pointed out the point of SQL Injection. Important topic which I missed earlier during answering your question. Please have a look at: https://www.owasp.org/index.php/SQL_Injection
For the very least please update your code to following:
