Question

我在cakephp验证中遇到了问题。下面我描述我想要做的事情：

<select>
<option> Value 1</option>
<option> Value 2</option>
</select>

Input 1 : <input type="text" name="val1" value="" />
Input 2 : <input type="text" name="val2" value="" />

假如我从下拉列表中选择“值1”，则“输入1”文本框将被验证，如果我从下拉列表中选择“值2”，则“输入2”文本框将被验证。

我如何在cakephp验证中执行此操作？请帮帮我..这是非常紧急的.plsssss

尝试使用Cake FormHelper类来构建表单 - 它几乎可以为您完成所有操作并且可以自定义http://book.cakephp.org/2.0/en/core-libraries/helpers/form.html

HTML

<select name='select_val'>
    <option value='val_1'>Value 1</option>
    <option value='val_2'>Value 2</option>
</select>

Input 1: <input type="text" name="val1" value="" />
Input 2: <input type="text" name="val2" value="" />

MyModel.php

public $validate = array(
    'select_val' => array(
        'rule' => 'customValidationForInputs',
        'message' => 'Invalid value'
    )
);

public function customValidationForInputs($check) {
    if ($check['select_val'] == 'val_1') {
        //access the value in 'val1' through $this->data[$this->alias]['val1']
        //perform some checks on the value
        if (the value in 'val1' passes your checks) {
            return TRUE;
        }
        else {
            return FALSE;
        }
    }
    if ($check['select_val'] == 'val_2') {
        //access the value in 'val2' through $this->data[$this->alias]['val2']
        //perform some checks on the value
        if (the value in 'val2' passes your checks) {
            return TRUE;
        }
        else {
            return FALSE;
        }
    }
    //if we reach here then the value of the select was not either of the ones specified so presume this is invalid
    return FALSE;
}

条件验证取决于cakephp中的字段
