Re: js only partially working

Hi!

A few things you might consider:
>> First debug your code and find the source of your problem, then post the small piece of code that is flawed so that we do not have to spit through all your code (which I, for one, am not going to)
>> If you are a novice in JavaScript, you might consider starting with easier things instead of adapting difficult code.
>> If you did not write the script, we can not help you fix it. Seek help at the author of the script.

Re: php rearange issue

1. You put each mile in an array and each name
2. You sort the miles-array: http://php.net/manual/en/function.sort.php or an equivalent function (you can always write your own -> good for learning)
3. You run through the array echo'ing each element.

Re: PHP login will not check level row

Umm, try this checklist:

A. Is "users" the correct table?
B. Is the name of the column that holds the level really "level", as you described on line 25?
C. You should have fixed it by now, if not, post a reply :)

Re: PHP login will not check level row

Hi tstory28,

After a quick look through your code, I would like to suggest a few things:

- Put a new if statement around line 6 to 61, in which you check whether the email and password form variable are set (if (isset($_POST['email) && .....) and delete the if statement in line 10

- Line 7, 8 - Clean the form value first: $variable = htmlentities(addslashes($_POST['form_variable'])); - Line 26 - Add an echo in which you show all the variables from the database:

echo "dbemail=".$dbemail.", dbpassword=".$dbpassword.", dbname=".$dbname.", dblevel=".$dblevel;

If you did all those steps (especially the last one), you will find out why your code is not working (probably because dblevel is empty, but you'll see)

Re: Calling a function twice, help appreciated

You need to encase your code in code tags, one that opens, one that closes (without the spaces between the []):

[CODE ] Some code.... [/CODE ]

Anyway, on to your code:

  • You misspelled getElementById by changing the 't' into a 'd'
  • You kind of messed up the brackets in the CheckAnswer() function

The code was written OK, so my complements for that ;) I adjusted the code a bit so that it is more commented and spaced:

var PlayerWins = 0;
var PlayerLosses = 0;

function CreateRandomNumber() {

  /* Calculating and returning random number between 0 and 100 */
  return Math.floor(Math.random() * (100 + 1));

}

function CreateRandomOperator(){

  /* Calculate random number between 0 and 1 */

  var Operator = "";

  var val = Math.floor(Math.random() * (1 + 1));

  if(val == 0) {
    Operator = "+";
  } else if (val == 1) {
    Operator = "-";
  }

  return Operator;

}

function CheckAnswer() {

  /* Retrieving the two numbers and the player's answer: */
  var Number1 = parseInt(document.getElementById('Number1').innerHTML);
  var Number2 = parseInt(document.getElementById('Number2').innerHTML);
  var Operator = document.getElementById('Operator').innerHTML;
  var Player_Answer = parseInt(document.getElementById('Player_Answer').value);

  /* First you check whether the answer is correct: */

  if (Operator == '+') {

    if(Player_Answer == Number1 + Number2){

        PlayerWins++

Re: could anyone check this code for me plsss?

Alright, I guess you stopped reading my posts which provided the solution and which only need one more adjustment to work with the table you described in your last post. Finding a solution when you show no effort on solving your OWN problem and use youtube films to learn PHP, is not going to work...

Good luck.

Re: Can anyone solve this simple HTML error

It's not the fault of the HTML nor CSS, if you would read the sourcecode, you would see that after every dot (.) there is a unknown character icon. This is caused by your editor that you use to type the text (your CMS perhaps), which adds a unknown character after every dot.

PS: You should validate your CSS using w3 CSS validator, on first glance, I saw that line 5 should be: font-style:none;

Re: Query thinks it is ok although it is not ?

I hope you set the variable $id in code you have not shown yet, and cleaned that with htmlentities() and addslashes(). If you are counting on register_global of PHP, you are creating a huge security leak. Well anyway, to solve your problem, you first need to select the row, check whether there is a row with that id (num_rows > 0) and then delete it:

$q1 = "SELECT * FROM databasemanager WHERE id='".$id."' LIMIT 1";
$r1 = mysql_query($q1) or die("Could not retrieve row. 1");

if (mysql_num_rows($r1) > 0) { // If the id exists

$q2 = "DELETE FROM databasemanager WHERE id='".$id."' LIMIT 1 ";
$r2 = mysql_query($q2) or die("Could not delete row. 2");

// The rest of your code...

}

Re: Javascript help onload function

Thats fairly easy:

<script type='text/javascript'>window.onload=function(){ update(document.getElementById('qty')); }</script>

You should place this beneath the form HTML, so that the id already exists.

Hangman Source Code: Java

Hey everybody,

Lately I have written the game Hangman in many different languages (C, JavaScript, Java and PHP so far). Here is the code snippet for Java! It uses a words file, on the bottom of this post you will see a small example of a few words. The source code for other languages can be found here on DaniWeb and on my new website: http://www.hangman.symbolwebdesign.nl/.

Due to the fact it is not possible (in web apllications) to open a words file using Java, it is required to directly put the words string separated by a | into the string variable. Modify the string in the initGame() function in the script (line 59).

Re: Validate Form

>> You want the form to be checked before submitted:

Change the form tag into:

<form id="form1" name="form1" method="post" action="sendform.php" onsubmit='return isValid()'>

And the submit button into:

<input type="submit" name="button" id="button" value="Submit order" />

And the checkbox into:

<input type="checkbox" name="checkbox" id="checkbox"  value="agreed"/>

Then use the following javascript function:

function isValid() {
var checkbox = document.getElementById('checkbox').checked;
var mot = document.getElementById('Is Vehicle Roadworthy with Full M.O.T.').value;
if (mot == "Yes" && checkbox == true) {
	return true;
} else {
     if (mot != "Yes") {
	  alert("Your vehicle must be roadworthy with full M.O.T.");
	 }
	 if (checkbox != true) {
	  alert("You have to agree with the Terms and Conditions");
	 }
     return false;
}
}

>> You want to redirect the user after submitting

Place the following code at the end of sendform.php:

header('Location: http://www.n-v-m.co.uk/Thankyou.html');

Re: onclick event on submit in ie7

I see you found a solution for it yourself. However the way you solved is a bit on a cumbersome manner. If you want a form to not be submitted, you just adjust the form tag:

<form action="" method="post" onsubmit="return false;">
...
... The form
...
</form>

This way, also when the user presses the enter-button on his keyboard, the form won't be submitted.

Re: Applying AJAX / Good textbooks

I would first advice that you write the HTML code (or generate it in php). Then, when the page is shown properly, you start writing the AJAX-based functions one by one. This is to prevent that your code doesn't work and that you have no idea where it all went wrong.

I learned AJAX and alot of PHP from the book PHP 5 Advanced: Visual QuickPro Guide (2nd Edition)

A few links to online AJAX tutorials:

w3schools
Tizag

You can also Google yourself.

- How to debug your code
- How do you use an include() and how do you acces files beneath the webroot?
- How do you secure your site, what techniques can be used and what shouldn't you do.
- When should you use sprintf(), printf(), print(), echo() and how do you use them (%f,%d etc. and wether you should use single quotes(') or double quotes("))
