如何编写已经在php echo中的$ _SERVER [“PHP_SELF”]

Question

I have a form that is written in PHP that will call the page upon itself (I don't know if I say this right).

echo('</table>
<hr>
<h1 id="loadscript_h1">Voeg een loadscript toe</h1>
<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>" method="POST" enctype="multipart/form-data">
<div><input type="file" name="loadscript" id="loadscript" value="Kies loadscript"/></div>');
echo ('<input type="submit" class="formsubmit" name="upload_loadscript" value="Upload loadscripts" />
</form>');

But when I look at my website there is something written like this:

" method="POST" enctype="multipart/form-data">

How can I write this properly?

Answer 1

you have to use concatenation for strings. notice the '. which tells PHP to terminate string, then concatenate with the following. See the docs: http://www.php.net/manual/en/language.operators.string.php

echo '</table>
<hr>
<h1 id="loadscript_h1">Voeg een loadscript toe</h1>
<form action="'.htmlspecialchars($_SERVER["PHP_SELF"]).'" method="POST" enctype="multipart/form-data">
<div><input type="file" name="loadscript" id="loadscript" value="Kies loadscript"/></div><input type="submit" class="formsubmit" name="upload_loadscript" value="Upload loadscripts" />
</form>';

also, you don't need parenthesis for echo.
