Roly · August 1, 2004

Just post your PHP problem here and I will try to help you. Having trouble writing a script? I am here come to me here. And no offense but I think I know more PHP than the admin. BTW, I don't want you to think of me as a person who gloats about himself a lot because I don't. I'm just saying this because it's been proved and I'm sure there are other great PHP programers here and I ask them to come here and help asnwer your questions.

So, im making a chatroom in wml/php with no database. I have most of it covered but I have a few problems. When a user enters the chat he/she has to enter the nickname. After the user has entered one message the chatroom "forgets" the nickname so if he/she enters another message, the name wont be displayed. I tried using sessions and cookies and such but I cant get em to work.

Mind showing us some of your stuff, Roley? Do you have a portfolio of anything you've done?

chinfo · August 2, 2004

And please change the topic title, some people are bound to get offended by that and take it against you. Something like "PHP Help Center" will be sufficient.

Mind showing me your source? And yes cookies is the best way. Your source should look something like this:

<?php[br]if(isset($_POST['nickname'])[/br]  setcookie('nickname', htmlentities($_POST['nickname']), 999999);[br]?>[br][/br]<form>[/br]<input name=nickname value="<?= isset($_COOKIE['nickname']) ? isset($_COOKIE['nickname']) : NULL; ?>"[br]<input name=message><input type=submit value="Say It"></form>

[/br]And remember you need to set the cookie before you write anything to the page. That means before the <html> tag

You should go to http://php.resourceindex.com/ and search for one. Before I knew PHP I went to that site to get my scripts and I slowly learned from them. I still go sometimes just to look for some examples.

No, cookies are not the best way to go. Sessions are most definately better than cookies, assuming nothing needs to be 'remembered' outside of the current session.

Some browsers don't allow cookies, and some people turn them off (due to security threats etc), so if your site uses cookies, not all users will be able to view it - or some may even choose to leave based on this reason alone.

On the other hand, sessions always work. And the user can't disable sessions (unless they close their browser window).

And as for your code:

<?php[/br]if(isset($_POST['nickname'])[br] setcookie('nickname', htmlentities($_POST['nickname']), 999999);[/br]?>

Shouldn't it be:

<?php[/br]if(isset($_POST['nickname']) {[br]       setcookie('nickname', htmlentities($_POST['nickname']), 999999);[/br]}// edit: IF statements need to be enclosed in { }.[br][/br]?>

(edit: I read it wrong the first time)

[/br]And remember you need to set the cookie before you write anything to the page. That means before the <html> tag

Actualy the source for the page where user inputs his/her name is

<?php [/br]session_start( ); session_register("nick"); [br]header("Content-type: text/vnd.wap.wml"); [/br]echo "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>"; [br]echo "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\"" [/br]. " \"http://http://www.wapforum.org/DTD/wml_1.1.xml;; [br]?> [/br]<wml> [br]<card id="en" title="Enter nickname">[/br]<p>[br]<?php $session=session_id(); ?>[/br]</p>[br]<p>[/br]  [br]            <do type="accept">     [/br]            <go href="viewroom.php?nick=<?echo $session?>" method="post"> [br]            <postfield name="nick" value="$nick"/>  [/br]            </go> [br]        </do> [/br]        Enter nickname: [br]        <input title="nick" name="nick" type="text" /> <br/>  [/br]               [br]</p>[/br]</card>[br]</wml>[/br]

I dont think thats correct though.

I dont know if its neede but heres also the code for the page that writes the data into the file

<?php [/br]session_start(); [br]header("Content-type: text/vnd.wap.wml"); [/br]echo "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>"; [br]echo "<!DOCTYPE wml PUBLIC \"-//WAPFORUM//DTD WML 1.1//EN\"" [/br]. " \"http://http://www.wapforum.org/DTD/wml_1.1.xml;; [br]?> [/br]<wml> [/br]<card id="msgadd" title="message added">[br]<p align="center">[/br]<br/>Your message has been added[br]</p>[/br]<p><?php $session=session_id();  ?></p>[br]<p><a href="viewroom.php?nick=<?echo $session?>">Chat</a></p>[br][/br]<p>[/br]<?php [br][/br]//use the fopen() function [br]$fp=fopen("msgs.txt",  "r");   [/br]$data = fread( $fp, filesize( "msgs.txt" )); [br]fclose( $fp ); [br][/br]$fp2 = fopen( "msgs.txt", "w" ); [br][/br]//using the fputs() function [/br]fputs($fp2, " [br]<p> [/br]//I was just testing so dont even notice the session varaible below[br]$session: $msg <br/>[/br]</p> [br]". $data ); [/br]   [br]fclose($fp2);   [br][/br]?> [br][/br]</p>[/br]</card>[br]</wml>[/br]

Roly · August 3, 2004

I optimized your source, replaced doublequotes with singlequotes because it's faster and change your file functions a bit:

<?php [/br]session_start(); [br]header('Content-type: text/vnd.wap.wml'); [/br]echo "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>"; [br]echo '<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN\ '.[/br].' "http://http://www.wapforum.org/DTD/wml_1.1.xml;; [br]?> [/br]<wml> [br]<card id="msgadd" title="message added">[/br]<p align="center">[br]<br/>Your message has been added[/br]</p>[br]<p><?php $session=session_id();  ?></p>[/br]<p><a href="viewroom.php?nick=<?echo $session?>">Chat</a></p>[br][/br]<p>[br]<?php [/br]$data = file_get_contents('msgs.txt');[br][/br]$fp2 = fopen( "msgs.txt", "w" ); [br]fputs($fp2, ' [/br]<p> [br]//I was just testing so dont even notice the session varaible below[/br]'.$session.': '.$msg.' <br/>[br]</p> [/br]'. $data );   [br]?> [/br][br]</p>[/br]</card></wml>

I am making a page that has a text box to do an area code lookup. Can you give me some tips to make it work? I have a text box for the area code and then a Go! button. Here is the code for the text box/button:

[br]<form id="headerSearch" action="./index.html" method="get">[/br]<div>[br]<input class="text" type="text" value="Area Code Search"[/br]onFocus="if (this.value == 'Area Code Search') this.value=''; else this.select();"[br]onBlur="if (this.value == '') this.value='Area Code Search';" />[/br]<input type="submit" class="submit" value="Go!" />[br]</div>[/br]</form>[br]

How can I make this work with a PHP script?

Thanks![/br]Dennis

Roly · August 8, 2004

I'm not sure what you mean with getting that to work but I'll try to help. The way I would do it is I would put all the area codes in a database and then search the database to see if the area code submitted matches.

<?php[/br]// insert database connection here[br][/br]if(isset($_POST['area']))[br]{[/br]  $result = mysql_query('SELECT location FROM areacodes WHERE area = \''.$_POST['area'].'\'');[br]  if(mysql_num_rows($result) > 0)[/br]  {[br]    $row = mysql_fetch_row($result);[/br]    echo 'The area code you submitted is in '.$row[0].'.';[br]  } else[/br]    echo 'No matches were found for the area code you submitted.';[br]}[/br]?>[br][/br]<form id="headerSearch" method="post">[br]<div>[/br]<input class="text" type="text" name="area" value="Area Code Search"[br]onFocus="if (this.value == 'Area Code Search') this.value=''; else this.select();"[/br]onBlur="if (this.value == '') this.value='Area Code Search';" />[br]<input type="submit" class="submit" value="Go!" />[/br]</div>[br]</form>[/br]

ddwyer · August 8, 2004

Ok I am using this. I have a database called db2, and a table in db2 called 'area'. This is an example of an entry in that table:

acode=201
state=NJ
details: blah blah all the cities, etc.
zone: Eastern

Below, when you said

[br]('SELECT location FROM area WHERE area ....[/br]

What do I put in location? Can I echo a table of all the above variables for the query? Can I make this a popup box with the table in that?

[/br]<?php[br]// insert database connection here[/br]$db = mysql_connect("localhost", "root","");[br]mysql_select_db("db2",$db);[br][/br]if(isset($_POST['area']))[/br]{[br] $result = mysql_query('SELECT location FROM area WHERE area = \''.$_POST['area'].'\'');[/br] if(mysql_num_rows($result) > 0)[br] {[/br]   $row = mysql_fetch_row($result);[br]   echo 'The area code you submitted is in '.$row[0].'.';[/br] } else[br]   echo 'No matches were found for the area code you submitted.';[/br]}[br]?>[/br]

Roly · August 8, 2004

Oh ok that works better. Yes that is possible, this is how:

<?php[/br]// insert database connection here[br]$db = mysql_connect("localhost", "root","");[/br]mysql_select_db("db2",$db);[br][/br]if(isset($_POST['area']))[br]{[/br]$result = mysql_query('SELECT * FROM area WHERE acode = \''.$_POST['area'].'\'');[br]if(mysql_num_rows($result) > 0)[br]{[/br]  $row = mysql_fetch_assoc($result);[/br]  echo '<b>Area Code:</b> '.$row['acode'];[br]  echo '<b>State:</b> '.$row['state'];[/br]  echo '<b>Details:</b> '.$row['details'];[br]  echo '<b>Zone:</b> '.$row['zone'];[/br]} else[br]  echo 'No matches were found for the area code you submitted.';[/br]}?>
