kimjessen Posted January 22, 2015 Share Posted January 22, 2015 Hi Yes I start a new thread, this is probably the correct one. I have solved my problem almost. the result ends with the end of a parenthesis. see picture how do I get it deleted. <?php $dir = './data/test111'; $ddArray1 = scandir($dir,1); ?> <html> <head> <title>Select Drop Down List</title> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"> <select name="file"> <?php FOREACH($ddArray1 AS $file){ PRINT '<option value="'.$file.'">'.$file.'</option>'; } ?> </select> <input type="submit"/> </form> </body> </html> <?php if ($_POST) { echo '<pre>'; print_r($_POST); $test='</pre>>'; echo $test; } ?> Link to comment https://forums.phpfreaks.com/topic/294111-removal-of-brackets/ Share on other sites More sharing options...
CroNiX Posted January 22, 2015 Share Posted January 22, 2015 So it's showing up after you submit the form? Not sure if it's the forum doing it or your code converting the > to >, but try: if ($_POST) { echo '<pre>'; print_r($_POST); echo '</pre>'; } Link to comment https://forums.phpfreaks.com/topic/294111-removal-of-brackets/#findComment-1503674 Share on other sites More sharing options...
kimjessen Posted January 22, 2015 Author Share Posted January 22, 2015 the > are right not a err. yes it did make a difference, not for the better. but a difference is something. the result is here! Array([file] => test111-2015-01-22.csv) now I can almost imagine where the end brackets come from. but how do I get them removed? Moreover, many thanks for the help.

CroNiX Posted January 22, 2015 Share Posted January 22, 2015 That's because you're printing the whole array using print_r, which stands for "print array". If you want just the file, then do: if ($_POST) { echo $_POST['file']; //only echos the 'file' index from the $_POST array } Link to comment https://forums.phpfreaks.com/topic/294111-removal-of-brackets/#findComment-1503680 Share on other sites More sharing options...

kimjessen Posted January 22, 2015 Author Share Posted January 22, 2015 Hello again! It does not work as I expected. I would combine it with the graph, but I only get an error when I press the button. I understand: who is in error description but can it be solved, or do I need to have the graph to run on a page by itself. ? error message looks like this. " Explanation:HTTP headers have already been sent back to the browser indicating the data as text before the library got a chance to send it's image HTTP header to this browser. This makes it impossible for the library to send back image data to the browser (since that would be interpretated as text by the browser and show up as junk text).Most likely you have some text in your script before the call to Graph::Stroke(). If this texts gets sent back to the browser the browser will assume that all data is plain text. Look for any text, even spaces and newlines, that might have been sent back to the browser. For example it is a common mistake to leave a blank line before the opening "<?php".

Barand Posted January 22, 2015 Share Posted January 22, 2015 No guarantees, but try putting the php portion of your code in a separate file (mygraph.php) and use GET instead of post. In a separate php file put $id = whatever; echo "<img src='mygraph.php?file=$id' />"; Link to comment https://forums.phpfreaks.com/topic/294111-removal-of-brackets/#findComment-1503705 Share on other sites More sharing options...
kimjessen Posted January 22, 2015 Author Share Posted January 22, 2015 hey it works that's what I do today. I would like to have it on the same page. I think that I have to use a different graph library. possibly some java.

kimjessen Posted January 22, 2015 Author Share Posted January 22, 2015 hi guys you are just amazing. It works just as I had hoped for, again many thanks.
