PHP - Creating Time Sensitive Links
Hello,
I am completely new to php so please forgive me ahead of time. I am trying to create a link button on a website for a client that only directs to a certain external website on certain days and hours. Specifically, this is a web radio button that the client only wants to link to the web radio site when their live broadcast is on the air during certain hours on the weekend (i.e. Sundays 8-10 PM). Any other time, the client wants the web radio button to link to a default page since the web radio station plays unrelated music all other hours of the week. Does anyone know the best way to create such a time sensitive link for a button on a webpage? Thanks. Similar TutorialsI have taken over a wordpress site that a web developer set up and he is no longer working with me so I cant get his help with it, I have a custom front page that has been pulling press releases that where posted previously and categorized as "press" I was asked to add a blog which I did by categorizing the post as "blog" In a nutshell, I now need the front page code to pull a mixture of both the "press" and "blog" each category has a numerical id so blog is 7 and press is 3 This is the current code that is in the page <?php query_posts('category_name=press&showposts=10&offset=0'); ?> I looked up wordpress support for this, and found this query_posts(array('category__in' => array(2,6))); How can I integrate this if possible with the top line so it pulls the newest posts from both categories? Any suggestions could REALLY help me out! Thanks! Hey guys, I want to create stats of visitors and some other values in the database depending on time. The stats are supposed to be created one time per hour. What can I use for it? Cronjob? What will be if it doesn't work?? Thanks for helping! Hi there I've been working with some code to display a single record on page. This all works fine and I'm able to pull what I want from the database. My problems is trying to use that data and turning it into something else like a link. I have a field in the database called image url which contains rows of image urls. So here is the problem area of the code: Code: [Select] <?php //////Displaying Data///////////// $id=$_GET['id']; // Collecting data from query string if(!is_numeric($id)){ // Checking data it is a number or not echo "Data Error"; exit; } $fetch=mysql_query("select * from productfeeds where ProductID=$id "); $row=mysql_fetch_object($fetch); echo mysql_error(); echo "<table>"; echo " <tr><td><b>ProductID</b></td><td>$row->ProductID</td></tr> <tr><td><b>ProductName</b></td><td>$row->ProductName</td></tr> <tr><td><b>ProductPrice</b></td><td>$row->ProductPrice</td></tr> //problem area for me <tr><td><b>Image</b></td><td>$row->ImageURL</td></tr> echo "</table>"; I'm trying to edit this part of the code: <tr><td><b>Image</b></td><td>$row->ImageURL</td></tr> I've tried this: <tr><td><b>Image</b></td><td><a href='{$row['URL']}'> <img src='{$row['ImageURL']}'></a> and <tr><td><b>Image</b></td><td><a href='$row['URL']'> <img src='$row['ImageURL']'></a> //removed brackets but I'm just getting errors. Can you guys help please? Thank you very much. Hey Guys. I am trying to create a time dropdown and increment eat by an an hour until it is lless than or equal to the end time. I am using the DateTime class to accomplish this.
Now when I am trying to use a for loop to accompish this it does not work. Can anyone please help me out with this issue?
Below is the code that I have
$start_hour = new DateTime("now",new DateTimeZone("America/New_York"));
$start_hour->setTime(6,00);
$formatted_start_time = $start_hour->format("H:i:s");
$end_hour = mktime(11,45);
for($start_hour; $start_hour <= $end_hour; $start_hour->modify("+60 minutes"));{
echo "<select name='cat_display_timeslot'>";
echo "<option>{$formatted_start_time}</option>";

Hi guys, I'm currently in the process of making a simple social networking type site for a uni project and have basically everything i want except the ability to use AJAX to link to my profiles in the search bar. I have this code to generate my XML: Code: [Select] <?php // create simplexml object $xml = new SimpleXMLElement('<rss version="2.0"></rss>'); // add channel information $xml->addChild('channel'); $xml->channel->addChild('title', 'The Social Network'); $xml->channel->addChild('link', 'http://reecesayer.com/projects/template/XML/news.rss'); $xml->channel->addChild('description', 'example'); // query database for article data include("phpfunctions.php"); db_connect(); $link = "www.reecesayer.com/projects/template/testprofile.php?id="; $select='SELECT email, id FROM users'; $result = mysql_query($select) or die(mysql_error()); while ($row = mysql_fetch_assoc($result)) { // add item element for each article $item = $xml->channel->addChild('item'); $item->addChild('email', $row['email']); $item->addChild('link', $row['id']); //I wanted to add a link before the $row['id'] } // save the xml to a file $xml->asXML('profiles.xml'); header ('Location: http://reecesayer.com/projects/template/XML/profiles.xml'); ?> I need to add a partial URL (http://reecesayer.com/projects/template/testprofile.php?id=) before the row is called so that when the email is searched it provides a link to the profile depending upon the id (http://reecesayer.com/projects/template/testprofile.php?id=8) Is there an easier way to do this or am i going the long way around? I'm only storing the data in XML as i saw a tutorial for a livesearch script on another site. Cheers, Reece Hi Everyone, I'm semi-new to php and trying to create a site where I have only one includes file for my navigation (main_nav.inc) and 2-3 includes files (main_template.inc) that act as templates. I then call the the nav and the template in my index.php file. Everything was working fine until I decided I should use php have my links appear active depending on which page the user is on. Everything works totally fine if I insert the code for my nav (including both the html and php) into my main_template.inc file but when I make that code into it's own includes file (main_nav.inc), I get an error. I believe the issue is with using both single and double quotes in my code and wrapping that code in single quotes in my main_nav.inc file. Here is the code from my main_nav.inc file: <?php $main_nav = ' <div id="mainNav"><ul id="mainNav"> <li><a href="index.php" <?php if ($page=='index.php') { ?> class="active" <?php } ?>>Welcome</a></li> <li><a href="healthcare.php" <?php if ($page=='healthcare.php') { ?> class="active" <?php } ?>>Healthcare</a></li> </ul></div> '; // end main_nav ?> I think that since the code is wrapped in single quotes, I can only use double quotes in my code. This is the only difference I can figure out between inserting the code into the template directly (which works perfectly fine) and inserting it as a separate inc file. When I use the main_nav.inc file I get the following error: Parse error: syntax error, unexpected T_STRING in /home/content/k/a/l/kalilaks3/html/includes/main_nav.inc on line 11 I tried changing the quotes around ($page=='index.php') to ($page=="index.php") but that causes the browser to literally read the name of the link a class="active">Welcome I also tried variations of escaping quotes such as ($page==\"index.php\") and even escaping the other quotes and wrapping everything in double quotes as opposed to single quotes. Here is my code for my main_template.inc file <?php $page = basename($_SERVER['SCRIPT_NAME']); $page_title = "Welcome"; include_once ("includes/main_nav.inc"); // sets variable include_once ("home_template.inc"); // sets all variables ?> And here is my index.php file: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="healthcare" name="keywords"></meta> <meta content="healthcare" name="description"></meta> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title><?php echo $page_title; ?></title> <link rel = "stylesheet" href = "_css/layout.css"></link> <script type="text/javascript" src="scripts/script.js"></script> </head> <body> <div id = "header"><div id = "globalHeader"> <?php echo $main_nav; ?> </div></div> </body> </html> Any help or suggestions would be greatly appreciated!!! I would love to get this figured out so that I only have to create my navigation once for all my sites! Hi there, I am just wondering which way is the correct one if you want to create object properties/attribute dynamically at run time using magic method __set(), __get(), for example: class Foo{ public $data = array(); public function __set($name,$value){ $this->data[$name] = $value; } public function __get($name){ if ( isset($this->data[$name]) ){ return $this->data[$name]; } } } Or using the below way class Foo{ public function assign(array $data){ foreach($data as $key => $value){ $this->$key = $value; } } } I just encountered the second way in many places and I am totally confused . Is the __set() method called implicitly by the PHP engine in the second way or what? how come this is considered as a valid code ? your usual help is appreciated How do I make the username and password checking CASE SENSITIVE? $result=sprintf("SELECT * FROM db WHERE username = '%s' AND watchword ='%s'", mysql_real_escape_string($username), mysql_real_escape_string($password)); Thanks. Bickey. I need to make the following code work without case sensitivity. For example, if this was processed, I would like for $message to be changed from "Stupid is not a nice word. Ugly is not nice either." to "unintelligent is not a nice word. unattractive is not nice either." For my purposes, I don't care that the capitalization changes, I just need the $goodwords to be replaced with the $badwords regardless of capitalization. Any ideas here? Code: [Select] <?php $message = "Stupid is not a nice word. Ugly is not nice either."; $badwords = array("stupid", "ugly"); $goodwords = array("unintelligent", "unattractive" ); $message = str_replace($badwords, $goodwords, $message); ?> I am using preg_replace to automatically bold "$word" when it appears. It will only replace the word when capitalized. How can I get it to replace the word without being case sensitive. Also could I also throw a link in? I tried and I get a syntax error. I'm guessing the links in PHP are different than HTML Here is my code <?php $find ="/$word/"; $replace ="<b>$word</b>"; Echo preg_replace ($find, $replace, $definition); ?> Thanks when the simple search script in the tutorials on this site searches my mySQL database it doesnt find results unless they are typed in the same case as the original entry. ie 'horse' does not find 'Horse' is it some problem with my database table formats or do i need to add a bit of script to the search to solve it? This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=317710.0 I have the auto suggestion script. While the user is typing, results are printed below (from the database). The results are printed with bold letters that are in the search. However, this leads to errors in capitalization. The letters are replaced by users' queries, instead of from the database. Example: Search word: PHP Results: PHPfreaks, PHP tutorials But in the database this is the records: "phpfreaks" and "php tutorials". This is a script that replaces search letters with bolded: Code: [Select] $search = clean($_POST["search"]); $fname=$row['name']; //Record from database $re_fname='<b>'.$search.'</b>'; //Replace with bold letter $final_fname = str_ireplace($search, $re_fname, $fname); How to do a script that bold letters, but as they were in the database, not from search input? I am by no means a security expert, but I would like to know if storing MySQL database information in an environment variable would be a good or bad idea. What are your thoughts? PHP date and time function is not showing correct time on my local system I have the following php code date_default_timezone_set("Africa/Lagos"); $date = date('d-m-y h:i:s'); echo "Server Time ".$date ."<br>"; echo "The time is " . date("h:i:sa")."<br>"; $current_datetime = date("Y-m-d") . ' ' . date("H:i:s", STRTOTIME(date('h:i:sa'))); echo "Current time1: ".$current_datetime . "<br>";
Output
Server Time 21-05-21 09:55:39
Expected Output
Server Time 21-05-21 10:55:39
Any help would be appreciated. Edited May 21 by Ponel <html> <?php $id = $_GET['id']; $dbusername="web148-matt"; $dbpassword="matt"; $dbdatabase="web148-matt"; mysql_connect(localhost,$dbusername,$dbpassword); @mysql_select_db($dbdatabase) or die( "Unable to select database"); mysql_query("UPDATE count SET clicks=clicks+1 WHERE id='$id'"); $sql = mysql_query("SELECT link FROM count WHERE id='$id'"); $fetch = mysql_fetch_row($sql); $result = mysql_query("SELECT * FROM count"); while($row = mysql_fetch_array($result)) { echo "<a href=" .$row['link'].

What I am looking to do at this point is simply take the date/timestamp (part of the csv file), which is in the following format:DD/MM HH:MM:SS.100th/s For the sake of argument, lets say I have this in an array string called $csv[0] and the file has several lines that span the course of a couple hours. I wouldn't mind having to use explode() to breakup/remove the date or 100th/s IF that would make things a lot simpler. So where would I start in trying to achieve this?. The result I am looking for will simply return "X Seconds". Storing this in a string variable would be a bonus, as I plan to use this to divide a separate piece of information. Any examples or ideas would be great. Thank you. ps: Here is an example time from the csv file itself: Code: [Select] 11/19 22:23:18.143 I am trying to simulate an ad expiration and carry out an action if the ad is expired. And I cannot get the if/else to work properly... I've tried many variations and I cannot see what I am doing wrong here. Any tips please 3 hours and counting of no solution! $ad_start = time()-14 . "<br />"; // 14 days from today in the past (negative) echo $ad_start; $current_time = time() . "<br />"; // current epoch time echo $current_time; $days_past = $ad_start - $current_time; // days past echo "<br />$days_past days have past since the ad started!<br />"; if($days_past <= 14) { echo "<br />Ad is less than 14 days. Not expired."; } else { echo "<br />Ad is over 14 days. Expired."; }
What are the differences and implications of UTC time and Zulu time?

Hello, I tried to implement some PHP code to enable a web page to show "Dinner" specials versus "Lunch" specials based on the time. The business is located in the Eastern Time Zone, so I only need to routine to work based on Eastern Time (New York). What I am noticing is that the server is processing the lines of code so fast that the command to establish the correct time for the remaining code is not always being acknowledged. This line of code appears to be processing too fast for the remaining lines of code: date_default_timezone_set ( "America/New_York" ); Is there some additional code I can put in place to make sure the correct time is always ascertained? I need the $hourmin variable to always return a combination of hour + minute based on 24-hour time and Eastern Time zone. My code is as follows: <?php $name8 = file_get_contents("test/special8name.txt"); date_default_timezone_set ( "America/New_York" ); $gethour = date("H"); $getminutes = $gettimedate["minutes"]; $gettimedate = date(); $hourmin = $gethour . $getminutes; $currentday = date("l", time()); $currentdate = date("M j, Y"); if ($hourmin < 1500 && $currentday <> "Saturday" && $currentday <> "Sunday") { echo "<span class=\"namesred\">$name8 </span>"; } else if ( $hourmin > 1500 && $hourmin < 2300 && $currentday <> "Saturday" && $currentday <> "Sunday") { echo "<span class=\"namesblue\">$name8 </span>"; } else if ( $currentday == "Saturday" or $currentday == "Sunday") { echo "<span class=\"namesblue\">$name8 </span>"; } ?> |
