PHP - How Can I Mix A Font Tag With Php Database Variables?
Hi everyone, I'm trying to get my head around blending in and out of php and html. I've seen some simple examples which work great but now I have this variable that comes from the database and I would like to style the variable in-line with html markup.
Here's what I'm trying to do:
<?php
echo "Price : ",'<Font size="100"> $tournament["pricePerPlayer"] </font>';
....more of the same code goes here...
?>
I can't get $tournament["pricePerPlayer"] to be controlled by the font tag. How do I do this?
Any help would be greatly appreciated.
Thanks,

Each user will be associated with exactly one school. My query below works, but the thing that it returns is an array; I need to make use of it as a variable (say $instructor_school_id). Any idea how to make the conversion from a single element array into a non-array variable? Thank you.... function getInstructorSchool($read, $user_id) { $sql = "SELECT school_id FROM users WHERE user_id = $user_id"; return $read->fetchRow($sql); } Hiya I was wondering how one would get make dynamic url variable value pairs from a databases fields. I have a database that I want to use to store variable value pairs that will be used on my pages for dynamic content. It will check one thing for certain besides if the variable value pair match. The table looks like this rpg loc_type loc_type template I want it to check if the rpg is in an array and then check if the url variable and value pair match on from the database. I dont know much about auto code that would generate this on its own and I'm not sure if you can say $_GET[$location]; I dont want to hard code it so it only works with what i code I want the urls variable value pair to be based on the database info which determines which template to show based on those values. Hi friends, a quick print_r() shows the following array while connecting to my database. How to get them as individual items and display on the website ? Array ( [0] => Array ( [id] => 52 [document_name] => xyz [document_ext] => gif [download_file_name] => ktm_impact.gif [upload_dt] => 2010-08-11 ) ) Hola, I'm trying to create a web form to insert info into my database using session variables. I'm at my wits end at this point. The reset button does its job but when you click submit it doesn't do anything. I'm using the template from the lynda.com essential php web form tutorials.

I have some code which needs to return a single variable from the function and stored as a variable within this page, so it can be echoed later on in the page. I couldn't get it to return as a variable, so i used "return compact();" to return the variable and "extract (myFunction());" to extract it to variables. However, when I turned on php's display errors and error reporting function, I got an error message saying "Warning: extract() [function.extract]: First argument should be an array in /my/web/site/index.php on line 6" (which is where my extract function is). This works fine with passing more than one variables through, is there another way pass one variable from a function to be stored as a variable on the page which called the function? Here is the function: Code: [Select] <?php //This is a list of numeric error codes against their text. this will return the error code as the variable $issue function checkLoginIssue() { //If there is an error code if (isset($_GET["issue"])) { //cycle through the list until the code is reached, return the text and break the switch switch ($_GET["issue"]) { case "1": $issue = '<p class="warning">Please log in to view this page</p>'; break; case "2": $issue = '<p class="warning">Wrong Username or Password</p>'; break; case "3": $issue = '<p class="warning">No user found with those details</p>'; break; } //return the variable in an array with a single value return compact('issue'); } } ?> And here is the code which calls the function: Code: [Select] <?php extract(checkLoginIssue()); ?> hello everyone, I am about to start coding my pages to display results from a database but before i do i want to know information about the following : Is it best to upload images to a database?and display them accordingly? or is it best to use images from a directory? What is most commonly used and or more reliable? Another topic i have trouble finding information on is actually positioning the output from you mysql database, is this practice done with tables?fields and rows? What is this method called? And is there more then one way to go about controlling result layout on your page? Sorry about the 1001 questions , but i am unable to find a clear answer on the topic ..especially question two . Thanks in advance. I have a very tricky php problem here. At least for me. On a page that is editing a job entry. I have a database generated group of checkboxes some of which have been checked when the job was entered. So the script has to do two things generate the complete list of checkboxes and check the ones that have already been selected in the job request. The below script is what I've done trying to figure it out. Description of what I'm trying to do: I'm generating the the boxes with a call to my database for the list of checkboxes. Then I'm building an array with all the possible items that could be checked to compare against. Ok here is where I think my first problem is. I need to make a second query to another table "worklog" in the same database. This is where the list of checked items are stored. What is the best way to do this? A second query seems wrong "or at least not efficient" Code: [Select] <div class="text">Job Type (<a class="editlist" href="javascript:editlist('listedit.php?edit=typelist',700,400);">edit list</a>):</div> <div class="field"> <?PHP $connection=mysql_connect ("localhost", "user", "password") or die ("I cannot connect to the database."); $db=mysql_select_db ("database", $connection) or die (mysql_error()); $query = "SELECT type FROM typelist ORDER BY type ASC"; $sql_result = mysql_query($query, $connection) or die (mysql_error()); $i=1; echo '<table valign="top"><tr><td>'; while ($row = mysql_fetch_array($sql_result)) { $type = $row["type"]; if ($i > 1 && $i % 26 == 0) echo '</td><td>'; else if ($i) echo ''; ++$i; $aTypes = array ("Spec Ad Campaign", "100 x 100 Logo", "100 x 35 (Featured Developer/Broker)", "100 x 40 (Featured Lender)", "120 x 180 (Home Page Auto)", "120 x 45 (Half Tile - Jobs)", "120x60 (Section Sponsor)", "125 x 40 (Profile Page logo)", "135 x 31 (Autos)", "135 x 60 (Autos)", "135 x 60 (Logotile - Jobs)", "150 x 40 (Auto Logo)", "160 x 240 (monster tile)", "160 x 400 (Skyscraper)", "160 x 600 (Tower)", "170x30 (Section Sponsor)", "240 x 180 JPG/GIF Auto Video", "240 x 180 size FLV video ", "300 x 250 (Story Ad)", "300 x 600 (Halfpage)", "468 x 60 (Banner Jpg/Gif)", "728 x 90 (Leaderboard)", "95 x 75 (Sweeps Logo) ", "Agent Profile Page", "Contest", "Creative Change", "Employer Profile", "Holiday Shop", "Home of the Week", "HP Half Banner (234 x 60 Static)", "Mobile Ads (320x53 *300x50*216x36*168x28)", "Newsletter", "Peelback", "Pencil Ad", "Print", "Real Deals", "Resize ad campaign", "Roll-Over Skyscraper", "Site Sponsor logo (170x30)", "Splash Page Production", "Travel Deals Update", "Video Ad", "Web Development", "Web Maintenance", "Web Quote (or Design)"); $dbTypes = explode(',',$row['type']); foreach ($aTypes as $type){ if(in_array($aType,$dbTypes)){ echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type' CHECKED><span style='color:#000;'>$type</span></input><br/>"; }else { echo "<input style='font-size:10px;' name='type[]' type='checkbox' value='$type'><span style='color:#000;'>$type</span></input><br/>"; } } } echo '</td></tr></table>'; ?> </div> At the moment I am creating a search function for my website. The approach I have in mind is a pseudo-PHP database. To give an example: A HTML form will submit the results to a PHP file. HTML FORM - Colour: Black PHP RESULT PAGE - if ($_POST['color'] == 'Black') {readfile("./products/black/*.html");} HTML FORM - Price: <$50 PHP RESULT PAGE - if ($_POST['Price'] == '<$50') {readfile("./products/less50/*.html");} The problem here is if there is an item that is black and costs less than $50, then its going to be listed twice. There is probably some code I can write to ommit the listing of duplicate entries, but it is probably going to be messy, so I am wondering if its better to use a centralized MySQL database, rather than a pseudo-PHP database? I've never used MySQL and don't know much about it and this is my first real attempt at using PHP. after cloasing connection of database i still got the values form database. Code: [Select] <?php session_start(); /* * To change this template, choose Tools | Templates * and open the template in the editor. */ require_once '../database/db_connecting.php'; $dbname="sahansevena";//set database name $con= setConnections();//make connections use implemented methode in db_connectiong.php mysql_select_db($dbname, $con); //update the time and date of the admin table $update_time="update admin set last_logged_date =CURDATE(), last_log_time=CURTIME() where username='$uname'limit 3,4"; //my admin table contain 5 colums they are id, username,password, last_logged_date, last_log_time $link= mysql_query($update_time); // mysql_select_db($dbname, $link); //$con=mysql_connect('localhost', 'root','ijts'); $result="select * from admin where username='a'"; $result=mysql_query($result); mysql_close($con); //here i just check after closing data baseconnection whether i do get reselts but i do, why? echo "after the cnnection was closed"; if(!$result){ echo "cont fetch data"; }else{ $row= mysql_fetch_array($result); echo "id".$row[0]."usrname".$row[1]."passwped".$row[2]."date".$row[3]."time".$row[4]; } // echo "<html>"; //echo "<table border='1' cellspacing='1' cellpadding='2' align='center'>"; // echo "<thead>"; // echo"<tr>"; // echo "<th>"; // echo ID; // echo"</th>"; // echo" <th>";echo Username; echo"</th>"; // echo"<th>";echo Password; echo"</th>"; // echo"<th>";echo Last_logged_date; echo "</th>"; // echo "<th>";echo Last_logged_time; echo "</th>"; // echo" </tr>"; // echo" </thead>"; // echo" <tbody>"; //while($row= mysql_fetch_array($result,MYSQL_BOTH)){ // echo "<tr>"; // echo "<td>"; // echo $row[0]; // echo "</td>"; // echo "<td>"; // echo $row[1]; // echo "</td>"; // echo "<td>"; // echo $row[2]; // echo "</td>"; // echo "<td>"; // echo $row[3]; // echo "</td>"; // echo "<td>"; // echo $row[4]; // echo "</td>"; // echo "</tr>"; // } // echo" </tbody>"; // echo "</table>"; // echo "</html>"; session_destroy(); session_commit(); echo "session and database are closed but i still get values from doatabase session is destroyed".$_SESSION['admin']; ?> session is destroyed but database connection is not closed. thanks I have a standard form that displays users current data from a mysql database once logged in(code obtained from the internet). Users can then edit their data then submit it to page called editform.php that does the update. All works well except that the page does not display the updated info. Users have to first logout and login again to see the updated info. even refreshing the page does not show the new info. Please tell me where the problem is as i am new to php.
my form page test.php
<?PHP
require_once("./include/membersite_config.php");
if(!$fgmembersite->CheckLogin())
{
$fgmembersite->RedirectToURL("login.php");
exit;
}
?>
<form action="editform.php?id_user=<?= $fgmembersite->UserId() ?>" method="POST">

Hi guys, I was just wondering if anyone could help me. I've got a My_SQL database containing articles, a summary for the article and a date. I have a basic CMS system set-up, but I want to create a script that when users sign up to a mail list it forwards the summary and dates of the articles database. If that makes sense? But I only want it to forward the most recent 5 rows. I'm pretty new to PHP and I've been mostly following tutorials thus far, but this is quite specific. Thanks in advance! two questions, 1) what is the default font that is used? 2) if i wanted to change the font for the whole site, is that simple? I've been trying to create a [font] bb code for my site which would allow the attributes color, size and face, but and can't really think of any way it would work. Most of my regex is guesswork so I'm struggling with this a bit. The tag wouldn't strictly need any attributes and could be in any particular order, so it would be a lot like the html <font> tag. If anyone could point me in the right direction I'd appreciate it. here's what I have so far: $string = preg_replace('/\[font([\sface|\ssize|\scolor\]=](.+?)(\]|\s)+)/i','',$string); The bit where I've stumbled is the second parameter. I'm not really where I'd go from there. Anyway, if you can help me, cheers! I've been googling with very little sucsse to find out if and how I can define a certain font to be used in the message body wtih out the viewer having to have the font installed on there computer. Is this at all possible? In PHP when you post a form the default font is Times New Roman how do I changes the font to arial |
