html - PHP mySQL search not working - 


<?php      $username = "root";      $password = "";      $hostname = "localhost";       $db_handle = mysql_connect($hostname, $username, $password) or die ("could not connect database");       $selected= mysql_select_db("login", $db_handle);       $output='';       if(isset($_post['search'])){          $searchq = $_post['search'];           $query= "select * php_item name '%searchq%' or description '%serachq%'" or die ("could not search");          $result= mysql_query($query);          $count= mysql_num_rows($result);           echo $count;           if($count <1){              $output = 'there no search results';          }else{              while($row = mysql_fetch_array($query)){                  $mname = $row['name'];                  $price = $row['price'];                  $id= $row['itemid'];                   $output .= '<div>'.$mname.'

im trying impliment search bar on website users can enter name of movie , return movies same or similar name user's search.

the database being searched has 3 fields-->> itemid, name, description. keep getting 0 results 'there no search results' output. ideas problem is?

there few issues code.

firstly, left out dollar signs variables, technically-speaking, searching "searchq" or "serachq" literal strings. "serachq" being typo mentioned below.

'%searchq%' or description '%serachq%'

as per $searchq = $_post['search'];

plus, made typo in word serachq in like '%serachq%'

rewrite:

'%$searchq%' or description '%$searchq%'
  • checking errors have spotted those.

your or die ("could not search"); in query, doesn't help. see note below adding or die(mysql_error()) mysql_query().

then line:

while($row = mysql_fetch_array($query))

that should referencing $result in $result= mysql_query($query); , not $query

while($row = mysql_fetch_array($result))

add error reporting top of file(s) find errors.

<?php  error_reporting(e_all); ini_set('display_errors', 1);  // rest of code

sidenote: error reporting should done in staging, , never production.

also add or die(mysql_error()) mysql_query().

you have seems commented out code in html, , broken; double-check in:

<!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd"><!-- <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd"> --><!-- <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd"> --><!-- <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd"> --><!-- <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en"

  • which break page.

  • just change whole block <!doctype html>

your present code open sql injection. use prepared statements, or pdo prepared statements, they're safer.

conditional statements options:

this line: if(isset($_post['search'])) changed to

if(      isset($_post['search']) &&      !empty($_post['search'])      )

in order make sure input wasn't left empty.

or simply:

if( !empty($_post['search']) )
