Question

我无法从动态生成的txtinput []和MultiSelect获取POST值，因为它们形成了一个数组。我看了很多文章，但我感到困惑..

下面给出了我的代码的简短形式..

请以最佳方式帮助我如何以字符串“value1，value2，value3”的形式获取数组值

问候......谢谢...... 下面是我的代码

Answer 1

如果我理解正确，你应该试试这个

$phoneno = implode(', ',$_POST['phoneno']);

Answer 2

我设法用

做到了

foreach ($_POST['phoneno'] as $ph) {$phoneno.= $ph.", ";}
foreach ($_POST['lang'] as $lng) {$langs.= $lng.", ";}

从Array Elements获取POST值
