Question

I’m trying to create filtered search with opportunity to select prices from to

HTML:

<select id="selectbox2" name="from">
        <option value="x">Choose</option>
        <option value="500">500</option>
        <option value="1000">1000</option>
        <option value="1500">1500</option>
        <option value="2000">2000</option>
        <option value="2500">2500</option>
        <option value="3000">3000</option>
        <option value="4000">4000</option>
</select>
<select id="selectbox2" name="to">
        <option value="x">Choose</option>
        <option value="500">500</option>
        <option value="1000">1000</option>
        <option value="1500">1500</option>
        <option value="2000">2000</option>
        <option value="2500">2500</option>
        <option value="3000">3000</option>
        <option value="4000">4000</option>
</select>

PHP:

if ((isset($_GET['features'])) && ($to!='x') && ($from!='x') ){    
    $result = mysql_query("SELECT * FROM baldas WHERE kategorija = '$id2' 
        AND $features = 1  AND kaina BETWEEN '$from' AND '$to' 
        ORDER BY pavadinimas_lt  LIMIT $offset, $rowsPerPage") or die(mysql_error());
}
elseif ((isset($_GET['features'])) && ($to!='x') && ($from=='x') ){
    $result = mysql_query("SELECT * FROM baldas WHERE kategorija = '$id2'
        AND $features = 1 AND kaina BETWEEN '$from' AND 500000 
        ORDER BY pavadinimas_lt  LIMIT $offset, $rowsPerPage") or die(mysql_error());
}
elseif ((isset($_GET['features'])) && ($to=='x') && ($from!='x') ){
    $result = mysql_query("SELECT * FROM baldas WHERE kategorija = '$id2' 
        AND $features = 1 AND kaina BETWEEN 0 AND '$to' 
        ORDER BY pavadinimas_lt  LIMIT $offset, $rowsPerPage") or die(mysql_error());
}

The part if ((isset($_GET['features'])) && ($to!='x') && ($from!='x') ) is working fine, but when to or from is equal x is giving no results. Where is the problem?

Answer 1

This part:

elseif ((isset($_GET['features'])) && ($to=='x') && ($from!='x') ){

is wrong, because there you check BETWEEN 0 AND ‘$to’. And you check $to for ‘x’ so that turns out wrong ( BETWEEN 0 AND ‘X’). I’d recommend echo’ing the SQL Queries. You can easily fix this by changing the conditional parameters.
