PHP - What Do People Look For When They Want A Website?

I don't even know if this is physically possible due to latency, mechanical, etc...    But, the way my website is planned at the moment, a person submits basic info, hits "Create account" and then is taken to a new page with that basic information and an incremented unique id, based on last unique id entry read from database.    My concern is that if two people or more were making accounts within the same time frame and one person hits "Create account" before another person does, what if the wrong data is pulled? 

The unique ID I guess is the only thing being pulled, if 0, start at 1, whatever    But I wonder if I can temporarily hold data between two webpages before it is stored in the database finally when all fields have been filled.    Thanks for any help / ideas 

My apologize if this should be here since this involves SQL.

My user can register himself ( just an email ) to a mail list.
He will get a mail after that, but the message in the mail should differ:
If there are under 100 people in the DB he should get something like " you are one of the 100 first people ", if there are more then 100 people it should say " sorry, to late ".

I can seem to get it to work so help would be awesome
( ps, I kinda need an anwser fast :s )

 $DB->query("UPDATE ibf_members set gold=gold+5
WHERE id = {$ibforums->member['id']}");
}

Look at the bottom, ok so if the person wins the hangman game, it will show "Congrats" but then people will just beable to refresh the page, and that query will run again and again and that person will gain +5 gold each time....we need to fix this!! any help?

Hi All,

not sure if this is a php Q but maybe someone has experience with this.
I use a form for people to add an item to the bulletin board. Sometimes the loading of the page takes very long and people think it didn't work so they click reload and post the item twice. I thought of adding a loading.gif so people know they have to wait. Anyone know how and where to put that in?

Hi, guys.

I want to present different ads to visitors in different countries.  For example, if a visitor is in Australia, I want him/her to see a different ad from, say, a visitor from the UK. Can this kind of thing be done with PHP? If so, will installing such a code slow down my site?

Any help will be appreciated very much.

Hi, how much bandwidth is used for 1000 downloads per day or for each download? Is it safe to have no download limits? Thanks

My data input form is not working with the first few people who have tried to use it.

I think it is because they are putting ' or " or some other character that is not allowed into the database.  Any ideas how I can fix it?

Let's say I have an HTML page with a form that submits data via POST. A user can click on "View source" and see the variables used.

What's to stop them from making their own page that POSTs to the same destination using the same variables? Any way to prevent this?

Hi, I'm currently using a voting script, but have a problem with people voting more then once, and want to add a way to keep the voting unique and 1 per person via IP check can anybody assist me how to implement it in the following script please?

<?php

// the questions and the answers
$pool_question="Do you think I should keep Galaxy Universe open?";
$pool_option[1]="Yes";
$pool_option[2]="No";

// If counter files are not available,they will be created
// You may remove next lines after the first use of the script
        if (!file_exists("pool_5483543_1.txt")){
                // next two lines will not work if writing permissions are not available
                // you may create the files bellow manualy with "0" as their unique content
                file_put_contents ("pool_5483543_1.txt",0);
                file_put_contents ("pool_5483543_2.txt",0);
        }

// retrieve data saved in files
        $pool_responses[1]=file_get_contents("pool_5483543_1.txt");
        $pool_responses[2]=file_get_contents("pool_5483543_2.txt");


// if user votes, increase corresponding value
        if ($_POST["5483543"] and $_POST["5483543b"]==""){

                if ($_POST["5483543"]==2) {$pool_responses[2]++;file_put_contents("pool_5483543_2.txt",$pool_responses[2]);}
        }

// get percentajes for each answer in the pool
        // get total number of answers
        $total_responses=$pool_responses[1]+$pool_responses[2];
        if ($total_responses==0){$total_responses=1;}  // to avoid errors at start
        // compute percentajes (with one decimal number)
        $pool_percentaje[1] = round((100*$pool_responses[1])/$total_responses,1);
        $pool_percentaje[2] = round((100*$pool_responses[2])/$total_responses,1);
                                                                
// print the form, which includes de answers and the percentajes
print "<center>\n";
print "<form method=post action=".$_SERVER["PHP_SELF"].">\n";
print "<b>".$pool_question."</b>\n";
print "<table cellpadding=4>\n<br>";
// answer 1
print "<tr>\n";
print "<td><input type=radio name=5483543 value=1>  ".$pool_option[1]."</td>\n";
print "<td bgcolor=DDDDFF>" .$pool_responses[1]." (".$pool_percentaje[1]."%)</td>\n";
print "</tr>\n";
// answer 2
print "<tr>\n";
print "<td><input type=radio name=5483543 value=2>  ".$pool_option[2]."</td>\n";
print "<td bgcolor=DDDDFF>" .$pool_responses[2]." (".$pool_percentaje[2]."%)</td>\n";
print "</tr>\n";
print "</table>\n";
// a simple control to avoid one user to vote several times
if ($_POST["5483543"]){
        print "<input type=hidden name=5483543b value=1>\n";
}
print "<input TYPE=submit value=Add my answer>\n";
print "</form>\n";
print "</center>\n";

?>

The reason why I ask for IP check is I wan't to use 

$_SERVER["HTTP_X_MXIT_USERID_R"];

in the place of the Ip since it give a unique name via the platform I want to implement it.

Hello,

I am creating a website with the use of php and mysql. While I am not advanced, I've been learning quite a bit on php. However, I am looking to build a tracker type script and hide it into my coding so that if someone were to hack into my website and take my website coding, that it would send me an email notifying that they were using my coding.

How would I go about this? If you can help me, i'd be glad to credit you!

Thank you!

Hello everyone,

I'm in the process of creating a PHP script (will be open-source), I just need to know how to make it easy for people to add plugins?
Like I don't really know much about the concept of plugins (how they should work), all I know is that there should be a function to activate / deactivate the plugin, but how can I make it possible for people to run their "code" wherever they want?

I've heard about "hooks" but I don't really understand how this should work, anyone can explain please?

Thank you very much in advance

I'm trying to make a League of Legends (a video game) community website, both as a personal project and for practice.
Now the game has a lot of champions, each of whom have 5 unique abilities. Now, I thought about manually inputting all the details about each champion into a MySQL database, but that would long and tedious, and I don't really have the time for it now. Also, the game patches very oftern (like, once every 2 weeks) which changes many of the stats, etc. of the champion, and it is not possible for me to keep manually updating these every time there is a patch.

Fortunately, there is a League of Legends Wiki which has all the data I need in their specific champion pages, which they keep updated per patch. So I was wondering if there was any way to get the data from the divs in the wiki, and have it display on my site. What I want to do in my website is that whenever someone types a champion's name (in a post or whatever), I want it to display a hover-over dialog with some of the champions details. And a lot of other features such as that.

In plain English I need a way to :
> Tell PHP to go to the wiki's source code on a specific page
> Find a specific div container
> Get X data from there
> Pass X data into a function to display the hover-over

I think this way, I would not have to maintain a database as I can leech off the wiki's data.
I have not coded anything like this before, so I would like a few pointers as to how to achieve this. Any help will be appreciated!

I tried searching on google but couldn't find any relevant information, please redirect me to relevant source or help me with the code.

I want to pass a domain name in text field which will be scanned and then the script will display entire site map.

Not external links or links on a page. Sorry it is not easy for me to explain.

Eg. if i pass abc.com

Script will display

abc.com/12/adn.php
abc.com/asd/asd/
etc

Whatever their url format is.

All the links on that domain.
