    Running mySQL queries based on drop down options

    I have read some threads on here with regards to drop down menus and mysql queries, but can't find the answer I am looking for.

    Here goes:

    I have a search form and on selection of various dropdowns, I want these to create the mysql query on the search results.

    My HTML:

    <h1 class="red">Search Records</h1>
    <p>
    <form action="search.php" method="post" name="exchanges" id="exchanges">
    <select name="exchange" id="exchange" onclick="searchIt()" onblur="searchIt()">
    <option value="select" selected="selected">Select Search Field</option>
    <option value="id">Record Number</option>
    <option value="xchcode">Exchange Code</option>
    <option value="xchname">Exchange Name</option>
    <option value="xchcounty">Exchange County</option>
    <!--<option value="xchpcode">Exchange Postcode</option>-->
    <option value="xchcountry">Exchange Country</option>
    </select>
    &nbsp;
    <select name="sorting" id="sorting" onclick="searchIt()" onblur="searchIt()">
    <option value="select1" selected="selected">Sort By</option>
    <option value="id">Record Number</option>
    <option value="xchcode">Exchange Code</option>
    <option value="xchname">Exchange Name</option>
    <option value="xchcounty">Exchange County</option>
    <option value="xchpcode">Exchange Postcode</option>
    <option value="xchcountry">Exchange Country</option>
    </select>
    <select name="clauses" id="clauses" onclick="searchIt()" onblur="searchIt()">
    <option value="select2" selected="selected">Clause</option>
    <option value="=">Equals</option>
    <option value="like">Like</option>
    <option value="start">Starts With</option>
    <option value="end">Ends With</option>
    <option value="contain">Contains</option>
    </select>
    &nbsp;
    <select name="sortorder" id="sortorder" onclick="searchIt()" onblur="searchIt()">
    <option value="select3" selected="selected">Order</option>
    <option value="asc" name="1">Asc</option>
    <option value="desc" name="2">Desc</option>
    </select>
    &nbsp;<input type="text" name="searchdb" id="searchdb" size="25" onblur="searchIt()" style="left: 0px; top: 0px; width: 230px;" />
    &nbsp;&nbsp;
    &nbsp;
    <br />
    <br />
    <input type="submit" name="submit" id="submit" value="Search" />
    &nbsp;
    <input type="reset" value="Reset" onclick="searchIt()" name="Reset" />
    </form>
    My PHP (including query)

    <?php
    $select = $_POST['exchange'];
    $searchdb = $_POST['searchdb'];
    $select1 = $_POST['sorting'];
    $select2 = $_POST['clauses'];
    $select3 = $_POST['sortorder'];

    //To display friendly field name instead of actual field name
    if ($select == 'id')
    {
    $boxresult = 'Record Number';
    }
    if ($select == 'xchcode')
    {
    $boxresult = 'Exchange Code';
    }
    if ($select == 'xchname')
    {
    $boxresult = 'Exchange Name';
    }
    if ($select == 'xchcounty')
    {
    $boxresult = 'Exchange County';
    }
    if ($select == 'xchcountry')
    {
    $boxresult = 'Exchange Country';
    }

    //To use different queries while searching

    if ($select2 == '=');
    {
    $queres = "SELECT * FROM $db_name WHERE $select = '$searchdb' ORDER BY $select1 $select3";
    }
    else if ($select2 == 'like');
    {
    $queres = "SELECT * FROM $db_name WHERE $select LIKE '$searchdb' ORDER BY $select1 $select3";
    }
    else if ($select2 == 'start');
    {
    $queres = "SELECT * FROM $db_name WHERE $select LIKE '$searchdb%' ORDER BY $select1 $select3";
    }
    else if ($select2 == 'end');
    {
    $queres = "SELECT * FROM $db_name WHERE $select LIKE '%$searchdb' ORDER BY $select1 $select3";
    }
    else if ($select2 == 'contain');
    {
    $queres = "SELECT * FROM $db_name WHERE $select LIKE '%$searchdb%' ORDER BY $select1 $select3";
    }

    $query = $queres;
    $result = @mysql_query($query);
    $num = @mysql_num_rows($result);
    The queries are where I am having trouble. I know the syntax is correct because I have run it in phpMyAdmin and it works just fine.

    The trouble is, it won't select the right query when I click on search in the HTML. It seems to only run on the very last query no matter what option is selected.

    I hope I am making sense.

    Thanks guys and gals

    I don't have the else if in the php, I copied the code wrong. They should just be ifs only and not else ifs

    Looks like you have semi-colons after all your if statements? I'd delete them all and see where you are at.

    PHP Code:
    else if ($select2 == 'contain'); // DELETE ALL THESE ';'
    {
    $queres "SELECT * FROM $db_name WHERE $select LIKE '%$searchdb%' ORDER BY $select1 $select3";
