如何使用 php/mysql 显示/过滤搜索结果

Question

I'm very new to working with php / mysql coding, and I've got a slight problem with displaying results that are linked to an sql database.

At the moment people search using the below code - which works fine - it's a drop down select box, but you can only select one option. I want it so the items are check boxes and you can select more than one item.

I've included below the code that's used for when people input the data to the database - which are check boxes - and I have tried replacing the 'drop down select code' with this but it doesn't work.

Does anybody know what code I have to use to replace the 'drop down select code' so that checkboxes are viewable and you can filter more than one item - I have also included the 'results page code', which displays the results and I'm thinking that 'ClientStage' needs adding to the 'check box code' somewhere.

Sorry about my lack of knowledge with this and would be grateful for some help?

DROP DOWN SELECT CODE

<select name="ClientStage" id="ClientStage">
            <option value=""></option>
            <?php
        include 'Easyspace.php';
        $sql = 'SELECT * FROM `clienttype`;';
        $rs = mysql_query($sql, $conn) or die ("error with sql query ".$sql);

        while ($row = mysql_fetch_array ($rs)){
            $ClienttypeID = $row["ClienttypeID"];
            $Clienttype = $row["Clienttype"];

            echo '<option value="' .$ClienttypeID. '">' .$Clienttype. '</option>'; 
        }
        ?>
          </select></span>

CHECK BOX CODE

<table width="100%" border="0" cellspacing="1">
    <?php
    $side=1;  
    $sql = 'SELECT * FROM `clienttype`;';
    $rs = mysql_query($sql, $conn) or die ("error with sql query ".$sql);

    while ($row = mysql_fetch_array ($rs)){
        $ClienttypeID = $row["ClienttypeID"];
        $Clienttype = $row["Clienttype"];

        if ($side == 1){
            $side = 2;
            echo '<tr>';
            echo '<td><span class="RPATtext"><input type="checkbox" name="Clients[]" value="' .$ClienttypeID. '"> ' .$Clienttype. '</div></td>';

        } else {
            $side = 1;
            echo '<td><span class="RPATtext"><input type="checkbox" name="Clients[]" value="' .$ClienttypeID. '"> ' .$Clienttype. '</div></td>';
            echo '<option value="' .$ClienttypeID. '">' .$Clienttype. '</option>'; 
        }

    }
    ?>
    </table>

Here's your new results code. I hope it's what you were looking for. Pay attention to your code: try to puts vars in lowercase ($Country has to be $country, try to use PDO for MySQL, etc...).

<?php

$Country = $_POST['Country'];
$County = $_POST['County'];
/* change here */
$ClientStage = $_POST['Clients'];
$HealthIssues = $_POST['HealthIssues'];

include 'Easyspace.php';
$sql = "SELECT * FROM `therapists` WHERE ";

if ($Country){
    $sql .= "`Country` = '$Country'";
}

if ($County){
    if ($Country){
        $sql .= ' AND ';    
    }
    $sql .= "`County` = '$County'";
}

if ($ClientStage){
    if ($Country or $County){
        $sql .= ' AND ';    
    }
    /* change here */
    $sql .= 'Client_typeID IN (';
    foreach($ClientStage as $i => $id) {
       if ($i !== 0)
           $sql .=  ',';
       $sql .=  "'" . $id . '"';
    }
    $sql .= ')';
}

if ($HealthIssues){
    if ($Country or $County or $ClientStage){
        $sql .= ' AND ';    
    }
    $sql .= "FIND_IN_SET('$HealthIssues', IssuesID)";
}
// echo $sql;

$rs = mysql_query($sql, $conn) or die ("error with sql query ".$sql);

while ($row = mysql_fetch_array ($rs)){
    $TherapistID = $row['TherapistID'];
    $Title = $row['Title'];
    $FirstName = $row['First Name'];
    $LastName = $row['Last Name'];
    $PostCode = $row['PostCode'];

    echo '<tr>';
    echo '<td valign="middle" bgcolor="#D9E5C3" class="bodycopy">' .$Title. '</td>';
    echo '<td valign="middle" bgcolor="#D9E5C3" class="bodycopy">' .$FirstName. '</td>';
    echo '<td valign="middle" bgcolor="#D9E5C3" class="bodycopy">' .$LastName. '</td>';
    echo '<td valign="middle" bgcolor="#D9E5C3" class="bodycopy">' .$PostCode. '</td>';
    echo '<td height="34" valign="middle" bgcolor="#D9E5C3"><p class="bodycopy"><a href="Therapist.php?ID=' .$TherapistID. '">View more details</a></p></td>';
    echo '</tr>';

}

?>
