jimbob33 Posted October 28, 2006 Share Posted October 28, 2006 Hi there,I'm trying to write a php echo file to go with a html form.I need to count and show the total number of characters returned from the variables entered on the form.Where do I insert this and do I use count() or strlen() or neither? This may be simple but I'm new to php and struggling.Here is my php code so far - not sure if you need the code from my html form aswell.Thanks in advance.<html><body>Your favourite book is <?php echo $_GET["book"]; ?>.<br />Your favourite meal is <?php echo $_GET["meal"]; ?>.</body></html> Link to comment https://forums.phpfreaks.com/topic/25410-counting-characters-in-variable-returned/ Share on other sites More sharing options...
Skatecrazy1 Posted October 28, 2006 Share Posted October 28, 2006 Well how exactly are you retrieving the data from the user? because GET will only work if you usemethod="url" in the form. I suggest using the post method, then the way to count the string length of the submitted stuff is:[code]<?php$fav_book = $_POST['book'];$fav_meal = $_POST['meal'];$book_length = strlen($fav_book);$meal_length = strlen($fav_meal);//then echo itecho("<p>Your favorite book is $fav_book.</p>");echo("<p>Your favorite meal is $fav_meal.</p>");//and use the length variables however you want, you didn't really go into detail on that?>[/code]plus, the count function is used to count the number of values in an array, so it wouldn't be of use here.

jimbob33 Posted October 28, 2006 Author Share Posted October 28, 2006 Thanks for this but I have to use the 'get' method for college work. It's not for a live system.I am using it on a local web server - my own PC - so files are in the same place.

Skatecrazy1 Posted October 28, 2006 Share Posted October 28, 2006 well if someone is requiring you to use the get method, then just do the same thing as above, but change your form method to url and replace $_POST with $_GET and it should work Link to comment https://forums.phpfreaks.com/topic/25410-counting-characters-in-variable-returned/#findComment-115942 Share on other sites More sharing options...
