如何从PHP中的同名文本框中获取帖子 [英] how to get post from same name textboxes in php

问题描述

我有一个带有多个动态创建的文本框的表单，现在所有这些文本框都具有相同的名称，可以说txt，现在有什么方法可以在进行表单处理时使用方法，它们具有相同的名称.如果可能的话如何?

I have a form with multiple textboxes which are created dynamically, now all these textboxes are of same name lets say txt, now is there any way that when form processing happens we could read all the text boxes values using $_POST method, which are of so called same name. If possible how?

推荐答案

您必须命名文本框txt[]，以便PHP为您创建一个数字索引数组:

You have to name your textboxes txt[] so PHP creates a numerically indexed array for you:

<?php
// $_POST['txt'][0] will be your first textbox
// $_POST['txt'][1] will be your second textbox
// etc.    

var_dump( $_POST['txt'] );
// or
foreach ( $_POST['txt'] as $key => $value )
{
  echo 'Textbox #'.htmlentities($key).' has this value: ';
  echo htmlentities($value);
}

?>

否则，最后一个文本框的值将覆盖所有其他值！

Otherwise the last textbox' value will overwrite all other values!

您还可以创建关联数组:

You could also create associative arrays:

<input type="text" name="txt[numberOne]" />
<input type="text" name="txt[numberTwo]" />
<!-- etc -->

但是然后您必须自己照顾名称，而不是让PHP来做.

But then you have to take care of the names yourself instead of letting PHP doing it.
