[英]Regular Expression PHP Help with if not equal to
I am trying to use regular expressions to make my inventory upload script a little better. 我正在尝试使用正则表达式来使我的库存上传脚本更好一些。
I sell clothing and accessories. 我卖衣服和配件。 In my inventory file I have a field called ProductDepartment which is a combination of gender/item type.
在我的库存文件中,我有一个名为ProductDepartment的字段,它是性别/项目类型的组合。 I have a MySQL table for gender with the following values:
我有一个性别的MySQL表,其中包含以下值:
Mens = 1 Womens = 2 Unisex = 3
Departments in the uploaded file look like the following, for example. 例如,上传文件中的部门如下所示。
Mens Outerwear Mens Watches Womens Jeans Headphones
So basically Im trying to make a statment that goes, if $ProductDept contains Mens, set $gender_id = 1, if $ProductDept contains Womens, set $gender_id = 2, if $ProductDept does not contain either, set $gender_id = 3 所以基本上我试图做出一个判断,如果$ ProductDept包含Mens,设置$ gender_id = 1,如果$ ProductDept包含Womens,设置$ gender_id = 2,如果$ ProductDept不包含,请设置$ gender_id = 3
And I'm having trouble figuring out how to write the 3rd if statement correctly. 而且我无法弄清楚如何正确地编写第3条if语句。 Here's what I have.
这就是我所拥有的。
if(preg_match('/Mens/g', $ProductDept)) {
$gender_id = '1';
}
if(preg_match('/Womens/g', $ProductDept)) {
$gender_id = '2';
}
if( != preg_match('/Mens|Womens/g', $ProductDept)) {
$gender_id = '3';
}
Change !=
to !
改变
!=
来!
: :
if (!preg_match('/Mens|Womens/g', $ProductDept)) { ... }
You could also rewrite it using elseif as follows: 您也可以使用elseif重写它,如下所示:
if (preg_match('/Womens/g', $ProductDept)) {
$gender_id = '2';
} elseif (preg_match('/Mens/g', $ProductDept)) {
$gender_id = '1';
} else {
$gender_id = '3';
}
I'll do : 我会去做的 :
if(preg_match('/Womens/', $ProductDept)) {
$gender_id = '2';
} elseif(preg_match('/Mens/', $ProductDept)) {
$gender_id = '1';
} else {
$gender_id = '3';
}
