how do i extract values from an array to show on a html page

[rotaryfreak]

hello,

im trying to build an application that will incorporate a "forgot password" feature. in order for my feature to work correctly, i am asking the user to type in his/her email address and he/she will have to answer a security question.

<form id="form1" name="form1" method="get" action="emailRetrieve.php" >
        <label>Please enter your email address:</label><br/>
          <label> Email address: <input type="text" name="emailText" id="emailText" size="50" /><br/><br/>
 
              Secret Question: <br/>
              Secret Answer: <input type="text" name="secretAnswer" id="secretAnswer" size="49" /><br/>
 
        </label>
        <input type="submit" value="Submit"/>
        </label>
    </form>
 

in my php script, i created an array with only 3 questions. Every time the page is refreshed, or other users use the "forgot password" feature, i am implementing a random function which chooses a random index of the array and will hence display a different question every time.

my problem is, when i hardcode the php script into the html page right after the "Secret Question" it works perfectly fine and i see the questions randomly changing when the page is refreshed. The problem now is that i need to send that same question for verification in my database. I can not access this variable outside the .html page. Now, when i move the php block to another file, i can not randomly generate my question and insert it into the html page. i know i have to use the $_POST method but whatever i try is not working

can anyone shed some light on this? how to i use php to randomly generate an index in my array and then insert it into my html page?

the code that im using for my 3 random questions is:

 
 <?php
 
$securQueArr = array("1" => "what was your first car", "2" => "what is your mothers name", "3" => "which city were you born in");
$randInt = rand(1,3);
 
 
$securityQuestion = $securQueArr[$randInt];
 
?> 
 
any ideas?

In your form you need something like:

<p>Secret Question: <?php echo $securityQuestion; ?></p>

To display the question.

You will also need to send the $securityQuestion through to your processing script which can either be done with $_SESSION's or $_POST. I am going to recommend $_POST (which is less secure) because all you're doing is sending the question. To do that, I suggest having a hidden input with the question number as the value:

<input type="hidden" name="Q_Num" value="<?php echo $randInt; ?>" />

Then in your processing script you can get the question number used like:

// Validation of $_POST variables
$Q_Num = $_POST['Q_Num'];

it seems to be almost working :| i get an error:
Notice: Undefined variable: securityQuestion in C:\Program Files\Wamp Server\www\Movie Database\EmailPwd.php on line 20

and when i look at line 20, it's this line:

Secret Question: <?php echo $securityQuestion; ?>

strange because i do define the value in my script...but, at least now im getting some input after Security Question

any ideas?

Are you defining it above that line? Is the case all the same? If yes to both of those, post your page code and let me have a look.

:) worked perfectly. here's what i did. After you asked if it was defined, i included the entire php script above the Secret Question line, and modified my emailRetrieve.php $Q_Num = $_POST['Q_Num']; to $Q_Num = $_GET['Q_Num'];
now my question changed randomly AND i have access to it through my emailRetrieve.php script so i can validate it against the entry in my database. Everything works perfectly, thank you so much!

No problem, glad it works.

Didn't notice your form method was GET, but, if you're happy with that, then great ;)
