Destoon Setting a custom search method _php Instance

The first step:

Add two functions to the 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 = "All ";    $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) {     ". $v." ";    }    else{     ". $v." ";    }    }    $title. = "";    return $title;}

The first function means filter blanks to enter

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

Step Two:

On the module/sell/search.inc.php of the "= Isset" ($day)? Intval ($day): 0; Next insert

$chengse = Isset ($CHENGSE)? Intval ($CHENGSE): 0;

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

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

Then use it in the template file:

{Select_search (Chengse,sell, $chengse)}
