PHP联系人表单电话验证号码的正确数量

PHP联系人表单电话验证正确数量的

你好，

我有一个php表单，它在提交后验证内容。粘性php表单就是它的名称。当发现错误时，它会将用户数据保存在输入框中，这样用户就不必再次输入所有数据。

当提交电话号码时，我需要它来验证第一个输入框中是否有3个字符/数字，然后在下一个框中有3个，最后一个框是4个。现在的方式是，只要你在第一个输入框中输入数字，它就会在其他输入框中查找电话号码。因此，我希望在验证过程中添加一个最小字符/数字脚本。我现在有一个表格来验证它是一个数字。我还需要它来验证手机的每个输入框中的数字数量是否正确。我相信这只是将elseif语句改为just-if内部的另一个if，但这也不起作用。如有任何帮助，我们将不胜感激。艺术学院只教了这么多PHP，而不是这个。

这是验证电话号码的脚本的特定区域：

//validate the phone number
if(is_numeric($_POST['phone01'])) { 
        $phone = $_POST['phone01']. '-';
}elseif(is_numeric($_POST['phone02'])) {    
        $phone .= $_POST['phone02']. '-';   
}elseif(is_numeric($_POST['phone03'])) { 
        $phone .= $_POST['phone03'];
}else{  
    print '<p class="error">Please enter your Phone Number as 10 Number.</p>';
    $validate = FALSE;
}

这是表单本身的整个脚本的副本：

<?php 
// This page receives the data from itself and validates as well
//error reporting!
ini_set ('display_errors', 1);
//Shows all possible problem!
error_reporting (E_ALL);
// validate email  
function isValidEmail($email){
    return eregi('^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$', $email);
}

//show form
function show_form($firstName='',$lastName='',$businessName='',$email='',$phone01='',$phone02='',$phone03='',$message=''){
?>
<!--The form starts here -->

使用strlen验证字段长度。不要使用if/elseif，因为您希望验证所有三个输入。设置标志以跟踪电话号码的有效性。

$invalid_phone = false;
if((strlen($_POST['phone01']) == 3) && is_numeric($_POST['phone01'])) { 
        $phone = $_POST['phone01']. '-';
}else{
   $invalid_phone = true;
}
if((strlen($_POST['phone02']) == 3) && is_numeric($_POST['phone02'])) {    
        $phone .= $_POST['phone02']. '-';   
}else{
   $invalid_phone = true;
}
if((strlen($_POST['phone03']) == 4) && is_numeric($_POST['phone03'])) { 
        $phone .= $_POST['phone03'];
}else{
   $invalid_phone = true;
}
if($invalid_phone){
    print '<p class="error">Please enter your Phone Number as 10 Number.</p>';
    $validate = FALSE;
}

上面的代码只是检查3个字段中的任何中是否有数字，而不是所有。

为了实现你想要的目标，像这样的东西可以做到：

if (is_numeric($_POST['phone01']) && is_numeric($_POST['phone02']) && is_numeric($_POST['phone03']))
{
     $phone = $_POST['phone01']."-".$_POST['phone02']."-".$_POST['phone03'];
}
else
{
    print '<p class="error">Please enter your Phone Number as 10 Number.</p>';
    $validate = FALSE;
}

然而，上面的代码不进行任何其他类型的验证，例如检查是否在每个表单字段中都放入了所需数量的数字。您可能还想使用"ctype_digit（）"函数来确保只输入数字，而不是像1.3这样的数字字符串。

所以你可以做一些类似的事情

if (!ctype_digit($_POST['phone01']) || strlen($_POST['phone01']) != 4) 
{ 
    $validate = FALSE; 
}
