php form_validation,php – 没有实际表单的CodeIgniter Form_Validation

我想做的很简单(我希望)：

我正在尝试使用Form_Validation验证POST数据(或通过变量提供的任何数据).

问题是要运行我/我们需要做的实际验证

if ($this->form_validation->run() == FALSE){

//validation did not pass

}else{

//validation did pass

}

我的规则是这样的：

$this->form_validation->set_rules('key', '', 'trim|required'); //simplified

所以,我显然是通过AJAX向这个脚本发送数据

echo $_POST['key']; //prints valid value that is sent from AJAX

如何使用form_validation验证$_POST [‘key’]？

AJAX代码

$("#key-inputs .short, #key-inputs .long").change(function () {

var key = $(this).val();

var id = $(this).attr('name');

var table = $(this).attr('class');

var file = $('span .file').val();

var data = 'NULL';

$.post(file + "/edit",{

id:id,

key:key,

file:file,

table:table},

function(code, textStatus) {

data = code;

});

$(this).ajaxStop(function(){

if (data == 3) $(this).parent().fadeOut('slow', function() {}); //delete

if (data == 2) $(this).fadeOut(200).fadeIn(200); //update

if (data == 5) alert('not valid'); //update parameter is not valid input (depends on set_value rules)

//writeConsole(previous.val().outerHTML);

});

});

PHP代码//简化

if (!$this->input->is_ajax_request()) redirect('lang/translate/keys/'.$param);

//do work here

if ($key == "") {

//delete key

$this->lang_translate_model->DeleteKey($id, $table);

echo 3;

return TRUE;

}

$this->form_validation->set_rules('key', 'key', 'trim|required|max_length[56]|xss_clean|unique_file[lang_key:'.$param.']');

if ($this->form_validation->run() == FALSE){

//validation did not pass

echo 5;

}

所以我有一些(生成的)输入,如果..set_rules通过,我想在DB中进行更新.

如果输入为空它会删除自己(这很好)

解

TRUE / FALSE表是here

if ($this->form_validation->required($key)){

//validation did not pass

echo 5;

}

如果有参数传递,例如min_length [2];

$this->form_validation->min_length($key,'2');
