Question

$cat_id=$_GET['cat_id'];
$catEx = explode(' ',$cat_id);
foreach($catEx as $exCat)
{
    $looped .= 'ad_cat LIKE'.' '.'%'."$exCat".'%'.' OR '.'ad_title LIKE'.' '.'%'."$exCat".'%'.' OR '.'ad_sub_cat LIKE'.' '.'%'."$exCat".'%'.' OR '.'ad_description LIKE'.' '.'%'."$exCat".'%' ;
}

我需要这样做，以便搜索栏搜索多个单词。

Answer 1

如@aynber在评论中所述

使用sprintf

 sprintf ( 'column like "%%s%" or column like "%%s%"', 'string', 'string');

Answer 2

在每组您喜欢的条件周围加上括号，以便在每一列中检查每个值。

$cat_id=$_GET['cat_id'];
$catEx = explode(' ',$cat_id);
foreach($catEx as $exCat) {
    $looped .= "(ad_cat         LIKE '%$exCat%' OR 
                 ad_title       LIKE '%$exCat%' OR 
                 ad_sub_cat     LIKE '%$exCat%' OR 
                 ad_description LIKE '%$exCat%') OR ";
}
$looped = trim($looped,' OR '); //just added some spaces

Answer 3

您可以尝试使用此代码

$cat_id=$_GET['cat_id'];//cute cat
$catEx = explode(' ',$cat_id);
$looped = [];
foreach($catEx as $exCat) {
    $looped[] = "ad_cat         LIKE '%$exCat%' OR 
                 ad_title       LIKE '%$exCat%' OR 
                 ad_sub_cat     LIKE '%$exCat%' OR 
                 ad_description LIKE '%$exCat%'";
}
echo implode(" OR ",$looped);

您能帮我解决这个foreach循环吗？
