集体数据和jQuery

You can usually use something like this:

<form action="example.php" method="POST">
<input type="text" name="file_name[]">
<input type="text" name="file_name[]">
<input type="text" name="file_name[]">

to collect data under the same name, and access it in PHP like:

$file_name = $_POST["file_name"];
echo $file_name[0]; //first occurrence
echo $file_name[2]; //third occurrence

but when it comes to generating dynamic fields with jQuery, like this:

$("#example_table").append("<tr><td><input type="text" name="file_name[]"></td></tr>");

and submitting it with standard submit button within POST form, the outcome differs. Only the last occurrence gets passed but the array indexes represent consecutive letters of such, not exact, indicated field as above.

The question is, why and how to fix it?

您通常可以使用以下内容:

  

以相同的名称收集数据,并使用PHP进行访问,例如:

  $ file_name = $ _POST [“ file_name”];
 echo $ file_name [0];  //第一次出现
 echo $ file_name [2];  //第三次
  

 

但是在使用jQuery生成动态字段时,就像这样:

  $(“#example_table”)。append(“     ”);
  

 

并使用POST表单中的标准“提交”按钮进行提交,结果有所不同。 仅最后一次出现通过,但数组索引表示上述表示字段的连续字母,但并不完全。

问题是,为什么以及如何修复它?

    You can use single quote instead of double quote for file_name. Might be this is useful to you.

    $("#example_table").append("<tr><td><input type='text' name='file_name[]'></td></tr>");

    You have to remove another double quotes from the html string. You have two ways for that

    1. $("#example_table").append("<tr><td><input type=\"text\" name=\"file_name[]\"></td></tr>");
    
    2. $("#example_table").append('<tr><td><input type="text" name="file_name[]"></td></tr>');
    

    Maybe this will help.

    So, the problem is solved. It was all about using double quotes instead of single ones. Thank you for your participation and support.
