destoon Setting Custom Search Methods

Step 1:

Add two functions in include/global. fun. php

Function 1:

function loseSpace($pcon){
$pcon = preg_replace("/ /","",$pcon);
$pcon = preg_replace("/ /","",$pcon);
$pcon = preg_replace("/ 　 /","",$pcon);
$pcon = preg_replace("/\r\n/","",$pcon);
$pcon = str_replace(chr(13),"",$pcon);
$pcon = str_replace(chr(10),"",$pcon);
$pcon = str_replace(chr(9),"",$pcon);
return $pcon;
}

Function 2:

function select_search($name,$tb,$fid){
    global $db;
    $title="<select name=".$name."><option value= > All </option>";
    $r = $db->get_one("SELECT option_value FROM {$db->pre}fields WHERE name='$name' and tb='$tb'");
    $option_value=loseSpace($r["option_value"]);
    $ps = split("\*", $option_value);
    #var_dump($matchs);
    foreach ($ps as $s){
    // With * Segmentation 1| Available *=> 1,  Available 
     if(!$s){
    continue;
     }
     list($num,$word) = split("\|", $s);
     $result[$num] = $word;
    }     
    foreach($result as $n => $v)
    {
    if ($n==$fid){
     $title .=" <option value=".$n." selected>".$v."</option>";
    }
    else{
     $title .=" <option value=".$n.">".$v."</option>";
    }
    }
    $title .="</select>";
    return $title;
}

The first function means to filter the space carriage return

The second function generates a drop-down list based on name (custom field) tb (model) $fid (currently selected ID).

Step 2:

$day = isset ($day) in module/sell/search. inc. php? intval ($day): 0; Insert below

$chengse = isset($chengse)?intval($chengse):0;

In if ($vip) $condition. = "AND vip > 0 "; Add below

if($chengse) $condition .= " AND chengse=$chengse";

Then use in the template file:

{select_search(chengse,sell,$chengse)}
