ok currently i use these below coding to load more results from database

 

JS and HTML on index.php

<script type="text/javascript">
    $( document ).on( 'click', '.loadmore', function () {
         $(this).text('Loading...');
         var ele = $(this).parent('li');
          $.ajax({
            url: 'load.php',
            type: 'POST',
            data: {
              page:$(this).data('page'),
            },
            success: function(response){
              if(response){
                ele.hide();
                $(".news_list").append(response);
              }
            }
          });
    });
    </script>
///////////////////////////////////////////////////////////////////////////
<div id="container">
    <ul class="news_list">
    <?php
    
    $query=mysql_query("SELECT * FROM profiles WHERE Gender ='female' ORDER BY UserID DESC LIMIT 0 , $resultsPerPage");
    while($data=mysql_fetch_array($query)){
    $fname=$data['Fname'];
    $lname=$data['Lname'];
    echo "<table border='0'><tr><td><h3>$fname</h3></td><td>$lname</td></tr></table>";
    }
    ?>
    <li class="loadbutton"><button class="loadmore" data-page="2">More Records...</button></li>
    </ul>
    </div>

load.php

 

<?php
       if(isset($_POST['page'])):
     $paged=$_POST['page'];
    $sql="SELECT * FROM profiles WHERE Gender ='female' ORDER BY UserID DESC";
    if($paged>0){
           $page_limit=$resultsPerPage*($paged-1);
           $pagination_sql=" LIMIT  $page_limit, $resultsPerPage";
           }
    else{
    $pagination_sql=" LIMIT 0 , $resultsPerPage";
    }

    $result=mysql_query($sql.$pagination_sql);

    $num_rows = mysql_num_rows($result);
    if($num_rows>0){
    while($data=mysql_fetch_array($result)){
    $fname=$data['Fname'];
    $lname=$data['Lname'];
    echo "<table border='0'><tr><td>$fname</td><td>$lname</td></tr></table>";
    }
    }
    if($num_rows == $resultsPerPage){?>
     <li class="loadbutton"><button class="loadmore" data-page="<?php echo  $paged+1 ;?>">More Records...</button></li>
 <?php
  }else{
      echo "<li class='loadbutton'><span class='endload'> No More Data... </span></li>";
 }
  endif;
   ?>

what im trying to acheive is get search records the similar way when user submits the form on search.php then on the results.php few records show and when click on load more and more search records display.

 

Anyone?

You show no search form, nor do you show what you are trying to search for.  It would be near impossible to suggest a solution.

sorry bout that mate.

 

ok here is my search.php which i include in the php pages

 

 

<form action="results.php" method="post">
<select id="employment" name="employment" >
                <option value=" " disabled="disabled" selected="selected">Select Employment</option>
                <option value="Unemployed">Unemployed</option>
                <option value="Employed">Employed</option>
                <option value="Self Employed">Self Employed</option>
                <option value="Government Employed">Government Employed</option>
        </select>,         

<select id="maritalstatus" name="maritalstatus" >
                <option value=" " disabled="disabled" selected="selected">Select Marital Status</option>

<option value="37" selected="selected">7' (2.13 mts) plus</option>

</select>    
                  <input type="submit" name="submit" value="Find" class="submit">
</form>

 

then here comes the results.php which displays results accordingly

 

<?php
    if(isset($_POST['submit'])){                                                

            $employment = mysql_real_escape_string($_POST['employment']);
            $mstatus = mysql_real_escape_string($_POST['mstatus']);
            $agefrom = mysql_real_escape_string($_POST['agefrom']);
            $ageto = mysql_real_escape_string($_POST['ageto']);                    
            
            $criteria = array();
            if($employment !='')
            {
                $criteria[] = "Employment = '".$employment."'";
            }
            if($mstatus !='')
            {
                $criteria[] = "Maritalstatus = '".$mstatus."'";
            }
            if($agefrom !='' && $ageto !='')
            {
                $criteria[] = "YEAR(FROM_DAYS(DATEDIFF(CURDATE(), dob))) BETWEEN '".$agefrom."' AND '".$ageto."'";
            }
    
        $query = "SELECT * FROM profiles WHERE " . implode(' AND ', $criteria);
        $result = mysql_query($query);
        while ($row = mysql_fetch_array($result)){
                echo $age = userAge($dob= $row["dob"]).'';
        }
}
print_r($_POST);
?>

 

like the first posted above i wish to have option to load just 5 search by default and then a button to load more results matching the selected criteria from search.php

 

im not getting any idea how to achieve it

Assign your $criteria to a $_SESSION on initial load (the initial db pull).  Then you only need to pass the page count (5, 10, 15, 20...) in the $_POST

.

session_start();
$_SESSION['criteria'] = $criteria;  //assigned on initial results

Then on your sub. query (BTW mysql_* is deprecated) which pulls the next five records, assign the "criteria" from the $_SESSION.

if(isset($_SESSION['criteria']) && !empty($_SESSION['criteria'])) { //assign to local var if available
  $criteria = $_SESSION['criteria'];
  $sql="SELECT * FROM profiles WHERE Gender = $criteria['gender'] ORDER BY UserID DESC LIMIT 0 , $resultsPerPage";
}

The Internet is "stateless" which requires your criteria to be stored in a container like a session, cookie or database in order to hold that current "criteria".

hope that helps.

there is an issue here

 

i did it like this

 

<?php
    if(isset($_POST['submit'])){                                                
            $employment = mysql_real_escape_string($_POST['employment']);
            $mstatus = mysql_real_escape_string($_POST['mstatus']);
            $agefrom = mysql_real_escape_string($_POST['agefrom']);
            $ageto = mysql_real_escape_string($_POST['ageto']);                    
            
            $criteria = array();
            if($employment !='')
            {
                $criteria[] = "Employment = '".$employment."'";
            }
            if($mstatus !='')
            {
                $criteria[] = "Maritalstatus = '".$mstatus."'";
            }
            if($agefrom !='' && $ageto !='')
            {
                $criteria[] = "YEAR(FROM_DAYS(DATEDIFF(CURDATE(), dob))) BETWEEN '".$agefrom."' AND '".$ageto."'";
            }
            
            $_SESSION['criteria'] = $criteria;
            $query=mysql_query("SELECT * FROM profiles WHERE " . implode(' AND ', $criteria)." ORDER BY UserID DESC LIMIT 0 , $resultsPerPage");
            while($data=mysql_fetch_array($query)){
            $fname=$data['dob'];
            $lname=$data['Lname'];
            echo "<table border='0'>
            <tr>
            <td width='20%'>
            <img src='uploads/profiles/16022014045.jpg' class='loadimg'>
            </td>
            <td width='80%'>
            <h3>Balaswami Surraminiam</h3>
            <b>Age:</b> 60 <br/>    
            <b>Caste:</b> $fname <br/>
            <b>Height:</b> 4' 5'' <br/>
            <b>Profession:</b> Chartered Accountant <br/>
            <b>Location:</b> Badarpur Rly Township <br/><br/>
            <a href='#'>view profile</a>
            </td>
            </tr>
            </table>";
    }
}
print_r($_SESSION);
?>

 

now when i select employment, mstatus and age anyways by default selected from 18 - 25 the query only outputs employment and age the mstatus does not show. what wrong am i doing here???

 

also the session outputs like this

 

 

Array ( [criteria] => Array ( [0] => Employment = 'Government Employed' [1] => YEAR(FROM_DAYS(DATEDIFF(CURDATE(), dob))) BETWEEN '18' AND '25' ) )
