[SOLVED] PHP MySQL Search - Query to search selected columns from drop down menus


Recommended Posts

Hi,

 

I found some code on the internet and I have been trying to change it to work a little differently.

 

I have added a second drop down menu to the code and added parts to the SQL query but it always returns the same error;

 

Notice: Undefined variable: dropdown1 in C:\wamp\cmstesting\test1.php on line 87

 

Notice: Undefined variable: search1 in C:\wamp\cmstesting\test1.php on line 87

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 'like ''' at line 1

 

 

Here is the code:

 

<html>
<head>
<basefont face="Arial">
</head>
<body>

<?php
error_reporting(E_ALL); 
if (!isset($_POST['Submit'])) {
// form not submitted
?>

<form action="<?=$_SERVER['PHP_SELF']?>" method="post">
search  
  <input type="text" name="search">
   <select size="1" name="dropdown">
    <option value="" selected>search By...</option>
    <option value="first">First Name</option>
    <option value="last">Last Name</option>
    <option value="company">Company</option>
    <option value="address">Street Name</option>
    <option value="town">Town</option>
    <option value="city">City</option>
    <option value="postcode">Postcode</option>
    <option value="mobile">Mobile Number</option>
    <option value="phone">Phone Number</option>
    <option value="email">Email Address</option>
    <option value="website">Web Address</option>
  </select>
  <br>

search1 
<input type="text" name="search1">
<select size="1" name="dropdown1">
  <option value="" selected>search By...</option>
  <option value="first">First Name</option>
  <option value="last">Last Name</option>
  <option value="company">Company</option>
  <option value="address">Street Name</option>
  <option value="town">Town</option>
  <option value="city">City</option>
  <option value="postcode">Postcode</option>
  <option value="mobile">Mobile Number</option>
  <option value="phone">Phone Number</option>
  <option value="email">Email Address</option>
  <option value="website">Web Address</option>
</select>
<br>
<input type="Submit" value="Submit" name="Submit"> 
</form>





<?php
}

else {

// Server Variables
$host = "localhost";
$user = "root";
$pass = "…….";
$db = "test";

$search = empty($_POST['search'])? die ("ERROR: Enter search Criteria") : mysql_escape_string($_POST['search']);
$dropdown = empty($_POST['dropdown'])? die ("ERROR: Select from dropdown") : mysql_escape_string($_POST['dropdown']);


// Open Connection

$connect = mysql_connect($host, $user, $pass) or die ("Unable to connect to host");

//Select Database

mysql_select_db($db) or die ("Unable to connect to database");

//Create query

$query = "SELECT * FROM contacts WHERE $dropdown like'$search' AND $dropdown1 like '$search1'" or die (mysql_error());


$result = mysql_query($query) or die (mysql_error());

$num=mysql_numrows($result);

mysql_close($connect);

echo "<b><center>Database Output</center></b><br><br>";

$i=0;
while ($i < $num) {

$first=mysql_result($result,$i,"first");
$last=mysql_result($result,$i,"last");
$company=mysql_result($result,$i,"company");
$address=mysql_result($result,$i,"address");
$town=mysql_result($result,$i,"town");
$city=mysql_result($result,$i,"city");
$postcode=mysql_result($result,$i,"postcode");
$mobile=mysql_result($result,$i,"mobile");
$phone=mysql_result($result,$i,"phone");
$email=mysql_result($result,$i,"email");
$website=mysql_result($result,$i,"website");

echo "<b>$first $last</b><br>Company: $company<br><br>Street Name: $address<br>Town: $town<br>City: $city<br>Postcode: $postcode<br>Mobile: $mobile<br>Phone: $phone<br>Email: $email<br>Website: $website<br><hr><br>";

$i++;

}
}
?>
</body>
</html>

 

I have also tried this;

$query = "SELECT * FROM contacts WHERE $dropdown='$search' AND $dropdown1='$search1'" or die (mysql_error());

 

Many thanks for any help…
