RonnieCosta50 Posted May 8, 2013 Share Posted May 8, 2013 I have a textbox and a submit button. It's easy to make an echo so whatever is typed in the textbox, echos under the textbox. I want to do something a little more complicated. I want to run the php code that is entered in the textbox. For example if I put this in the textbox <?php echo"Hello World";?> or if I put an if statement in the textbox I want it to run it. I am trying to learn php and it would be great if I could just input code into a textbox to see the result rather than have to upload the file to the FTP server every time. Sometimes I'm not at my home computer and I want to sample some code I read on the php manual. Question: Is it possible to run php code that is typed into a textbox? <!DOCTYPE html> <html> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Learn PHP</title> </head> <body> <form method="post"> <input name="txtTextbox" style="width: 500px" type="text"><br> <?php $txtTextbox = $_POST['txtTextbox']; $search = $_POST['btnSubmit']; if ($search) { // Here's the part I need help on. echo '<p>';?> $txtTextbox; <?php echo '</p>'; // Assume I typed Hello World <?php echo $txtTextbox;?> in the textbox } echo'<br>'; ?> <input name="btnSubmit" type="submit" value="submit"> </form> </body> </html> Link to comment https://forums.phpfreaks.com/topic/277796-run-code-typed-directly-into-a-textbox/ Share on other sites More sharing options...
davidannis Posted May 8, 2013 Share Posted May 8, 2013 You can but it is a huge security risk on a publicly accessible server. I would suggest installing WAMP, MAMP, or similar on your local machine. No uploads, it is easy to install, speeds development, and you don't have a server on the net that can be easily hacked. ?AMP (W for windows, M for Mac) will put Apache (webserver), MySQL, and PHP on you local machine.

RonnieCosta50 Posted May 8, 2013 Author Share Posted May 8, 2013 Yeah now that you said it I guess if someone know my website then they could type php code to ask for the connection details and then they have all they need. Guess it's a bad idea. Thanks . Link to comment https://forums.phpfreaks.com/topic/277796-run-code-typed-directly-into-a-textbox/#findComment-1429105 Share on other sites More sharing options...
buzzycoder Posted May 8, 2013 Share Posted May 8, 2013 Yes,its possible.Below is the code for it: <html> <head> <title>Execute PHP Code</title> </head> <body> <form action="" method="post"> <textarea name="code" cols="50" rows="20"></textarea><br> <input type="submit" name="submit" value="Execute"> </form> <?php if (isset($_POST['submit'])){ $code = $_POST['code']; eval("?> $code <?php "); } ?> </body> </html> Hope it helps you!

RonnieCosta50 Posted May 8, 2013 Author Share Posted May 8, 2013 Thanks for the code. It didn't work though but I modified it to work. Here is the code that worked for me for anyone else who reads this and wants to do this. Note: you should not do this. It's a security risk. I'm doing it because I have nothing on my server space and I'm learning php with it so I don't have to keep uploading the file to the server. <html><head><title>Execute PHP Code In A Textbox</title></head><body> <form action="" method="post"> <textarea name="code" cols="50" rows="20"></textarea><br> <input type="submit" name="submit" value="Execute"> </form> <?php if (isset($_POST['submit'])){ $code = $_POST['code']; eval($code); } ?> </body></html> Link to comment https://forums.phpfreaks.com/topic/277796-run-code-typed-directly-into-a-textbox/#findComment-1429158 Share on other sites More sharing options...
buzzycoder Posted May 9, 2013 Share Posted May 9, 2013 You're Welcome! I know that its not good if you're using it for your live sites as anyone can execute his bad codes & can harm your server.You said on your post that you're testing it on local machine.So,offcose you will not harm your machine by executing bad codes.I tested it & it works Good! can I know issues you're getting while executing mine code.Your code was Good too,but you only remove php tags from the eval.Its still same & will give same output too.I really appreciate that it helps you!
