You won't be able to have a short and unique number, simply because there are so many combinations a short number will be able to support.<br /> If you need the numbers to be unique and random, my suggestion is to use uniqid(). The number will be large, but that's the price you pay to have an unique number. </p> https://legacy.forums.gravityhelp.com/topic/random-chanracters-in-hidden-field#post-6753 Mon, 28 Jun 2010 01:36:25 +0000 helloari 6753@https://legacy.forums.gravityhelp.com/ <p>but how can i make sure that number has not been used before? it needs to be unique and sort and random... </p> https://legacy.forums.gravityhelp.com/topic/random-chanracters-in-hidden-field#post-5273 Wed, 05 May 2010 14:47:46 +0000 Alex Cancado 5273@https://legacy.forums.gravityhelp.com/ <p>Try using mt_rand() instead.<br /> For example, mt_rand(5,15) will generate random numbers between 5 and 15.

You can also control the minimum and maximum number generated by mt_rand() by passing them as parameters. For example: mt_rand(5,15) will generate random numbers between 5 and 15.<br /> You can find more info on mt_rand() here:<br /> <a href="http://www.php.net/manual/en/function.mt-rand.php" rel="nofollow">http://www.php.net/manual/en/function.mt-rand.php</a></p> <p>Good Luck. </p> https://legacy.forums.gravityhelp.com/topic/random-chanracters-in-hidden-field#post-1392 Mon, 09 Nov 2009 06:21:27 +0000 Raintrader 1392@https://legacy.forums.gravityhelp.com/ <p>Hi Alex,</p> <p> i also used te above posted Snippet in my function.php ans it works properly that way.<br /> Is there a way to influence the random text that is created ?<br /> Using this function generates text like this : 4af6b98a935f9<br /> Is it possible to to generate a random numeric string like : 89571547852 instead ?</p> <p>Thanx in advance</p> <p>Sascha </p> https://legacy.forums.gravityhelp.com/topic/random-chanracters-in-hidden-field#post-1198 Mon, 26 Oct 2009 18:32:59 +0000 RobertLBasil 1198@https://legacy.forums.gravityhelp.com/ <p>Carl,</p> <p>Yes, I am sending them to a wordpress page.

Are you using the built in confirmation page text and the form field variables, or are you redirecting to a page and passing the values in the query string?</p> <p>If you are redirecting to a WordPress page and passing the values in a query string you will need to use PHP to pull in those values and display them. Once you redirect to another page it is outside Gravity Forms control so you need to use PHP to manipulate the data in the query string.</p> <p>If you are using the built in text confirmation by entering your confirmation text in the form settings, the form field variables should work. If you are doing it this way, are you saying the form field variables for your hidden fields aren't working? If this is this case, have you verified that values exist for those hidden fields by viewing the Entry and checking to see that you are in fact storing the hidden field data? </p>
