Destoon set a custom search method _php Instance

First step:

Add two functions to include/global.fun.php

Function One:

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), "", $pcon);
$pcon = Str_replace (CHR), "", $pcon);
$pcon = Str_replace (Chr (9), "", $pcon);
return $pcon;
}

Function Two:

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) {
    //* Split 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 filtering a space carriage return

The second function generates a Drop-down list based on the name (custom field) TB (owning model) $fid (the currently selected ID).

Step Two:

$day = Isset ($day) in the module/sell/search.inc.php? Intval ($day): 0; Insert below

$chengse = Isset ($CHENGSE) intval ($CHENGSE): 0;

In the IF ($VIP) $condition. = "and vip>0";

if ($CHENGSE) $condition. = "and chengse= $chengse";

Then use in the template file:

{Select_search (Chengse,sell, $chengse)}
