我在一份PHP处理文件上有以下内容。

if(isset($_FILES[ cv ])){
    // run function here
}

唯一的问题是,这一职能正在获得全部时间...... 只有在档案已经投入的情况下才能操作吗?

问题回答

当出现同一名称的构成要素时,总是确定关键值。 你们可以测试一个空洞的档案。 这里有一条方式:

if(isset($_FILES[ cv ]) && $_FILES[ cv ][ size ] > 0){
    // run function here
}

如果你正在检查档案是否正确上载,请检查:

$_FILES[ cv ][ error ] == UPLOAD_ERR_OK

我认为,浏览器在用户事先选择文件时,会寄出一个空洞的田地,但的确会寄出文件,这样可以确定。

if(isset($_FILES[ cv ]) && $_FILES[ cv ]!=null && $_FILES[ cv ]!=""){
   //Execute
}
