Hi Guys.

 

I have the following PHP code querying results based on 4 combo filter boxes and would like to insert some pagination. I have found some pagination code that also works fine, but whenever I try to combine/merge the two PHP codes, I get some errors.... :shrug:

 

Here is the php that queries the mysql database:

<form name="input" action="" method="post">
Make: <Select name="make">
<option "Input" value="<?php echo $_POST['make']; ?>"><?php echo $_POST['make']; ?></option>
<option value="All Makes">All Makes</option>
<option value="Ford">ford</option>
<option value="BMW">BMW</option>
<option value="Honda">Honda</option>
<option value="Lexus">Lexus</option>
</select>

Model: <Select name="model">
<option "Input" value="<?php echo $_POST['model']; ?>"><?php echo $_POST['model']; ?></option>
<option value="All Models">All Models </option>
<option value="Civic">Civic</option>
<option value="3 Series">3 Series</option>
<option value="Fiesta">Fiesta</option>
<option value="IS200">IS200</option>
</select>

Fuel: <Select name="fuel">
<option "Input" value="<?php echo $_POST['fuel']; ?>"><?php echo $_POST['fuel']; ?></option>
<option value="Any">Any</option>
<option value="Petrol">Petrol</option>
<option value="Diesel">Diesel</option>
</select>

Location: <Select name="location">
<option "Input" value="<?php echo $_POST['location']; ?>"><?php echo $_POST['location']; ?></option>
<option value="UK">UK</option>
<option value="London">London</option>
<option value="Kent">Kent</option>
</select>

<input type="submit" value="Search Cars" />
</form>


<?php
include 'db.inc.php';

//variables from selection form
$make = mysql_real_escape_string($_POST['make']);
$model = mysql_real_escape_string($_POST['model']);
$fuel = mysql_real_escape_string($_POST['fuel']);
$location = mysql_real_escape_string($_POST['location']);

//default query
$query .= "SELECT * FROM `cars`";

//count the selections for queries
$query_count = 0;

//set queries and associate WHERE,AND
if(isset($_POST['make']) && $_POST['make'] != "All Makes" && $_POST['make'] != ""){
$query_count = $query_count +1;
if($query_count == 1) {
$where_and = "WHERE";
} else {
$where_and = "AND";
}
$query .= " $where_and Make='$make'";
}

if(isset($_POST['model']) && $_POST['model'] != "All Models" && $_POST['model'] != ""){
$query_count = $query_count +1;
if($query_count == 1) {
$where_and = "WHERE";
} else {
$where_and = "AND";
}
$query .= " $where_and Model='$model'";
}

if(isset($_POST['fuel']) && $_POST['fuel'] != "Any" && $_POST['fuel'] != ""){
$query_count = $query_count +1;
if($query_count == 1) {
$where_and = "WHERE";
} else {
$where_and = "AND";
}
$query .= "  $where_and Fuel='$fuel'";
}

if(isset($_POST['location']) && $_POST['location'] != "UK" && $_POST['location'] != ""){
$query_count = $query_count +1;
if($query_count == 1) {
$where_and = "WHERE";
} else {
$where_and = "AND";
}
$query .= "  $where_and Location='$location'";
}

//echo $query;//query built from values above depending on selections
$result = mysql_query("$query");

//check if results
if(!$result){
echo "No Results <br />";
} else {

echo "<table class='ex1' border='0' width='120%' style=text-align:center; cellpadding='6' cellspacing='0'>

</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr style=font-family:verdana;font-size:80%;>";

    echo "<td width=13%>" . $row[""] . "<img src=\"" . $row["Photo"] . "\"></a>";
    echo '<td width="14%"><a class="mylink" href="' . $row['URL'] . '">' . $row['Make'] . '</a></td>';   
    echo '<td width="5%"><a class="mylink" href="' . $row['URL'] . '">' . $row['Model'] . '</a></td>';
    echo '<td width="4%"><a class="mylink" href="' . $row['URL'] . '">' . $row['Fuel'] . '</a></td>';
    echo '<td width="4%"><a class="mylink" href="' . $row['URL'] . '">' . $row['Location'] . '</a></td>';
       
echo "</tr>";
  }
echo "</table>";
}

mysql_close($con);

?>

 

 

Here is the pagination code I am using:

<?php

include 'db.inc.php';
$per_page = 5;

//count of pages which is displays amount of page if you want to count rows you need to remove the divide sign
$pages_query = mysql_query("SELECT COUNT('id') FROM cars");

//add echo before dollar pages below if you want to show count of rows or pages
$pages = ceil(mysql_result($pages_query, 0) / $per_page);

$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$start = ($page - 1) * $per_page;

//query here
$query = mysql_query("SELECT * FROM `cars` LIMIT $start, $per_page");

//get results
while($query_row = mysql_fetch_assoc($query)) {

//show results
  echo "<p>" . $query_row['Model'] . "</p>";
}

//show number of pages at footer
if ($pages >= 1 && $page <= $pages) {

for ($x =1; $x<=$pages; $x++ ){
   echo ($x == $page) ? '<strong><a href="?page='.$x.'">'.$x.'</a></strong> ' : '<a href="?page='.$x.'">'.$x.'</a> ' ;

}

}
?>

 

Both PHP codes work fine seperately, but dont know how to merge them... :confused:

 

Can anyone help me on this?

 

Thanks! :)

Let me know if this doesn't work:  It is Un-tested!

<?php
include 'db.inc.php';

//variables from selection form
$cars['Make'] = mysql_real_escape_string($_POST['make']);
$cars['Model'] = mysql_real_escape_string($_POST['model']);
$cars['Fuel'] = mysql_real_escape_string($_POST['fuel']);
$cars['Location'] = mysql_real_escape_string($_POST['location']);

//make sure all $cars variables hold a value;
//set it to an array if it does.
foreach($cars as $key => $value) {
if(!empty($value)) {
	$query_string[] = "$key = '$value' ";
}
}

//default query, with added parameters.
$query = "SELECT * FROM `cars` WHERE " . implode('AND ',$query_string);

/*paganation starts =================*/
$per_page = 5;
$page_query = str_replace('*','COUNT(*)',$query);
$page_result = mysql_query($page_query) or trigger_error(mysql_error());
$count = mysql_fetch_row($page_result);
$row_count = $count[0];
//add echo before dollar pages below if you want to show count of rows or pages
$pages = ceil($row_count / $per_page);

$page = (isset($_GET['page'])) ? (int)$_GET['page'] : 1;
$query .= ' LIMIT ' . (($page - 1) * $per_page) . ',' . $per_page;


//echo $query;//query built from values above depending on selections
$result = mysql_query($query);

//check if results
if(!$result){
echo "No Results <br />";
} else {

echo "<table class='ex1' border='0' width='120%' style=text-align:center; cellpadding='6' cellspacing='0'>

</tr>";

while($row = mysql_fetch_array($result))
  {
  echo "<tr style=font-family:verdana;font-size:80%;>";

    echo "<td width=13%>" . $row[""] . "<img src=\"" . $row["Photo"] . "\"></a>";
    echo '<td width="14%"><a class="mylink" href="' . $row['URL'] . '">' . $row['Make'] . '</a></td>';   
    echo '<td width="5%"><a class="mylink" href="' . $row['URL'] . '">' . $row['Model'] . '</a></td>';
    echo '<td width="4%"><a class="mylink" href="' . $row['URL'] . '">' . $row['Fuel'] . '</a></td>';
    echo '<td width="4%"><a class="mylink" href="' . $row['URL'] . '">' . $row['Location'] . '</a></td>';
       
echo "</tr>";
  }
echo "</table>";
}
//show number of pages at footer
if ($pages >= 1 && $page <= $pages) {
 for ($x =1; $x<=$pages; $x++ ){
   echo ($x == $page) ? '<strong><a href="?page='.$x.'">'.$x.'</a></strong> ' : '<a href="?page='.$x.'">'.$x.'</a> ' ;
