如何使用PHP处理动态生成的javascript代码并将结果作为电子邮件发送？

Question

this is the javascript code

$(function () {
    var scntDiv = $('#p_scents');
    var i = $('#p_scents p').size() + 1;

    $('#addScnt').live('click', function () {
        $('<p><label for="p_scnts"><input type="text" id="p_scnt" size="20" name="p_scnt_' + i + '" value="" placeholder="Input Value" /></label> <a href="#" id="remScnt">Remove</a></p>').appendTo(scntDiv);
        i++;
        return false;
    });

    $('#remScnt').live('click', function () {
        if (i > 2) {
            $(this).parents('p').remove();
            i--;
        }
        return false;
    });
});

this is the html code

<h2><a href="#" id="addScnt">Add Another Input Box</a></h2>

<div id="p_scents">
    <p>
        <label for="p_scnts">
            <input type="text" id="p_scnt" size="20" name="p_scnt" value="" placeholder="Input Value" />
        </label>
    </p>
</div>

i'm trying to collect all the inputs generated and process them with php

Answer 1

1- Add a <form> tag before #p_scents so all the new <input type="text" ... are inside the form. Close the tag after #p_scents with ` and add a submit button or javascript function. In the form action you can add the same name of the file you are in (assuming it can handle php), otherwise create a php file.

2- Then you need to create a foreach loop in the php file to search for all the inputs. Colect them with $_POST.

You can do this way:
When you add new fields you can just keep them identicall and serialize them. Use name="p_scnt[]" in all input fields. The one already in the html and identical for all the generated by javascript. This will serialize them.

In the php file use: foreach($_POST["p_scnt"] as $value) { … }, inside the { } you can writhe your php code.

3- About making email from the variables you will have it's recomended to use some email library to avoid header injection, but anyway here is an example:

$to      = '[e-mail]';
$subject = 'Subject here';
$message = "Content";
$message .= "more Content";
$message .= "even more Content or a variable".$variable;
$headers = 'From: [e-mail]' . "
" .
'Reply-To: [e-mail]' . "
" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);

Hope this helps.
