删除空白答案的PHP表单提交 - 如果字段为空，请停止提交正文消息 [英] PHP Forms Submission with blank answers removed - Stop body message from submitting if field is blank

问题描述

短版php 我有一个表格，包含两个部分。申请人和合作申请人。我试图得到它，如果共同申请人的领域是空的或不需要的 php 文件不会发布提交的所有空白字段，因为我结束了两页标题和没有输入。表单通过电子邮件发送。

我刚刚添加了合作申请人部分，它隐藏在 div 之内显示何时选中复选框。

这是我正在处理的页面。
https://sundenmanagement.com/home1/index.php/test
完整的PHP代码 - 我试图用_co结尾所有字段，最后只在有文本输入时提交。所以如果没有共同申请人，它不会打印所有提交的标题。

（$ body_message。='名字：'。$ field_first_name_co。\r\\\
;）这些部分打印为名字：我不希望他们打印任何东西，如果他们是空的

解决方案

您可以通过对表单字段名称的轻微返工来简化维护工作。例如，脚本中的这一行：

  $ body_message。='离开原因：'。$ field_cur_reason_leaving。\ r\\\
; 
  

如果您将此表单字段名称更改为 $ reason_for_leaving 在你的HTML中 - 并为其他字段做同样的事情 - 你可以处理你的表单并生成你的电子邮件消息： c $ c> $ body_message =''; （$ key ='somethingspecial'）{
//特殊解析对于这个字段
} else {
//一些基本的清理
$ _POST [$ key] = trim（stripcslashes（strip_tags（$ value）））;
if（$ _POST [$ key]！=''）{
//如果字段不为空，则使表单字段名称
//看起来不错，并将值表单域
$ body_message。= ucwords（str_ireplace（'_'，''，$ key））。'：'。 $值。 \r\\\
;
}
}
}

显然，您需要为特殊的表单域（如复选框）做更多的工作，但这会大大简化您的代码（和您的生活）。

short version of php I have a form with two parts to it. An applicant and co applicant. I am trying to get it so that if the co applicant fields are empty or not required the php file will not post all the blank fields on submit as I end up with two pages of titles and no input. The form is emailed on Submit.

I just added the co applicant section and it is in a hidden div that shows when a check box is selected.

This is the page I am working on. https://sundenmanagement.com/home1/index.php/test Full PHP code - I am trying to gert all fields with _co at the end only submit when there is text input. so if no co applicant it will not print all the filed titles.

($body_message .= 'First Name: '.$field_first_name_co."\r\n";) these sections print as First Name: and I dont want them to print at all if they are blank

解决方案

You could make this a lot easier to maintain with a slight rework of your form field names. For example, this line in your script:

$body_message .= 'Reason for Leaving: '.$field_cur_reason_leaving."\r\n";

If you change this form field name to $reason_for_leaving in your HTML--and do the same for the other fields--you could process your form and generate your email message like this:

$body_message = ''; // initialize email body

foreach ( $_POST as $key => $value ) {
    if ($key == 'somethingspecial') {
        // special parsing for this field
    } else {
        // some basic sanitization
        $_POST[$key] = trim(stripcslashes(strip_tags( $value )));
        if ($_POST[$key] != '') {
            // If field isn't blank, make the form field name
            // look nice and add the value for the form field
            $body_message .= ucwords(str_ireplace( '_', ' ', $key )) .': '. $value . "\r\n";
        }
    }
}

Obviously, you'll need to do a little more work for special form fields (like your checkboxes), but this should greatly simplify your code (and your life).
