PHP - Function To Retrieve Newest Record
Hi there,
Before I begin, I want you all to know that I've been learning PHP for nearly a month now, so apologies for the poorly-written code that's going to follow. Two of my buddies and I are working on building a small website that allows us to play around with PHP and MySQL, since we work on an actual site that always in need of coding help. I tried searching for similar threads on this forum, but I couldn't find anything that answers my questions. I'm trying to accomplish a few things here. I have a form that allows us to add a record into a table (hunting consisting of the following columns: id, title, date, data, added_by. What I want to do is write a function that retrieves the newest record added to that table, call that function in a different file (it'll appear on the home page), and add a link to that record. If that sounds confusing, then this is what I want to do: 1. Retrieve last record added to the Hunters DB with a function. 2. Call that function in main.php, where it displays the record and format it like "Latest News: Title of the record" 3. I want to embed the link in the "Latest News: <Title of the record>", so it's clickable (this should be easy for me to do). But I need it to use the id (this is the primary key) column, which changes if a new record is added. Format: www.mysite.com/hunters.php?id=1 (the id value changes if a record with an ID 3 is added, so all I have to do is change the 1 to 3 in my browser to access that new record). This is what I wrote (functions.php): Code: [Select] function getNewHunterNews() { global $huntersdb; // Global that connects to the Hunters db $query = mysql_query( "SELECT `id`, `title` FROM `hunters_news` ORDER BY `id` DESC LIMIT 1", $huntersdb ); while ( $row = mysql_fetch_assoc( $query ) ) { $id = $row['id']; $title = $row['title']; } return $row; } In main.php (functions.php is included in this file): Code: [Select] <?php $huntnews = getNewHunterNews(); ?> <div id="news"> Latest News:<br /><br /> <span class="bolddark"><?php echo "<a href="\"/hunters.php?id={$huntnews['id']}\">" . $huntnews['title'] . "</a>"; ?></span> </div> I make the above changes, and my main page white screens. D: I know it isn't my function, because I've written simpler functions that are called in main.php, and those work. The white screen happens whenever I make the change above to main.php. What am I doing wrong? I'm fairly certain the change to main.php is causing problems, but I can't seem to point out what it is. Is there a different approach I can should take? I'm still in the learning process, so please guide me in the right direction. Additionally, if there any suggestions or constructive criticism you'd like to throw at me, please feel free. Every bit helps. Thanks in advance for your help! Similar TutorialsHere is what I am trying to accomplish: I have a students table with a studentID I also have a notes table and a sched table with studentID The sched table is working as planned where if the student is scheduled for more than one time he is displayed twice. However if there are multiple notes per student the student is display for each individual note where I would like only the most current note to be displayed Here is what the output is: 1- 10:30:00 - 10:50:00 student3 Three FST Teacher One Special1 One Writing Ratios 09/10 2- 10:30:00 - 10:50:00 student3 Three FST Teacher One Special1 One Needs to work on fractions and decimals 09/10 3- 13:00:00 - 14:00:00 student3 Three FST Teacher One Special1 One Writing Ratios 09/10 4- 13:00:00 - 14:00:00 student3 Three FST Teacher One Special1 One Needs to work on fractions and decimals 09/10 As you can see I have two notes and two schedule times for this student. what I want it to display is only line 1 & 3. which is the newest note in the system. Below is my code that I am using. Any help would be greatly appreciated. Code: [Select] <?php $result = mysql_query("SELECT * FROM students LEFT JOIN teachers ON students.teacherId = teachers.teacherId LEFT JOIN course ON students.courseId = course.courseId LEFT JOIN specialEd ON students.specialId = specialEd.specialId LEFT JOIN sched ON students.studentId = sched.studentId ORDER BY start "); echo "<table>"; while ($row = mysql_fetch_array($result)){ $id = "?id=" . $row['studentId']; echo "<tr>"; echo "<td>" . $row['start'] .

hi, i want to select the 5 newest records from a table in the database. the date they were entered is in a column called post_time and this is a timestamp(000-00-00 00:00:00). how would i go about this? Hi I have the following script to show images from a directory and make thumbs , but I would like to know how to sort the images from newest to oldest and how to implement it in this script
I'm a rookie at this...

Hi I'm currently wondering how people check for latest records each time they refresh only the latest records display in another color. For example a chat. When people submit post and another user refresh their chat page the newest post always get highlighted. Does it work with sessions or how does it work?
guys this function below posts the data into table and im also able to send a link in email with caregory name but the issue is getting the id to the particular post i got no isea how do i get that? Code: [Select] function insert($postData) { $postData['description'] = clean($postData['description']); if(!EmailExists($postData['email'])){ $sql = " INSERT INTO tbl_emails SET email = '".$postData['email']."', postersname = '".$postData['postersname']."', phone = '".$postData['phone']."' "; executeSql($sql); } if(empty($_FILES['image']["name"])){ $sql = " INSERT INTO tbl SET title = '".$postData['title']."', image = '', postersname = '".$postData['postersname']."', category = '".$postData['category']."', type = '".$postData['type']."', state = '".$postData['state']."', location = '".$postData['location']."', email = '".$postData['email']."', phone = '".$postData['phone']."', description = '".$postData['description']."', time = '".time()."' "; executeSql($sql); }else{ global $uploadPath; $remove_symbols = array('+', '=', '-', '{', '}', '$', '(', ')','&'); $removed_symbols = str_replace($remove_symbols, "_", $_FILES['image']['name']); $randomnum=rand(00000000,99999999); $imagepath = uploadFile($_FILES['image'], $uploadPath); $image = new SimpleImage(); $image->load($imagepath); $image->resize(250,280); $resize_rename = $uploadPath.$randomnum._.$removed_symbols; $image->save($resize_rename); unlink($imagepath); //delete the original file $sql = " INSERT INTO tbl SET title = '".$postData['title']."', image = '".$resize_rename."', postersname = '".$postData['postersname']."', category = '".$postData['category']."', type = '".$postData['type']."', state = '".$postData['state']."', location = '".$postData['ocation']."', email = '".$postData['email']."', phone = '".$postData['phone']."', description = '".$postData['description']."', time = '".time()."' "; executeSql($sql); } } I have a posting system worked out, as well as my database configured to my linking.. But as of right now, my posts are posted from oldest to newest, having users scroll down or go to the next page to see the most recent post.
How would I "flip" that around and make my posts start from newest to oldest by its date/time (Which is stored in the database)?
Thanks!
I have a variable $form in the code below what I cant figure out how do it is call it and get the information it has out so I can display the errors: Code: [Select] function login($subuser, $subpass, $subremember){ global $database, $form; //The database and form object /* Username error checking */ $field = "user"; //Use field name for username if(!$subuser || strlen($subuser = trim($subuser)) == 0){ $form->setError($field, "* Username not entered"); } else{ /* Check if username is not alphanumeric */ if(!preg_match("^([0-9a-z])*$^i", $subuser)){ $form->setError($field, "* Username not alphanumeric"); } } if ($database->usernameBanned($subuser)) { $form->setError($field, "*Your Account has been banned"); } /* Password error checking */ $field = "pass"; //Use field name for password if(!$subpass){ $form->setError($field, "* Password not entered"); } /* Return if form errors exist */ if($form->num_errors > 0){ return false; } /* Checks that username is in database and password is correct */ $subuser = stripslashes($subuser); $result = $database->confirmUserPass($subuser, md5($subpass)); /* Check error codes */ if($result == 1){ $field = "user"; $form->setError($field, "* Username not found"); } else if($result == 2){ $field = "pass"; $form->setError($field, "* Invalid password"); } /* Return if form errors exist */ if($form->num_errors > 0){ return false; } Hi, I am not very good with php but this code was kindly given to me by mdjamato, except I added a variable $markGradeSum to add all the $markGrade. Problem is that I will get notice saying undefined variable $markGradeSum because the $markGradeSum is in the foreach loop which it needs to be in for the right calculation but where I want to output the variable is in the while loop in this line: Code: [Select] $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong> <strong>Grade</strong> <br><strong>Year:</strong> {$row['Year'] $markGradeSum}</p>\n"; Below is whole code: Code: [Select] <?php if($num ==0){ echo "<p>Sorry, No Records were found from this Search</p>";} else{ function outputModule($moduleID, $moduleName, $sessionData) { if(!count($sessionData)) { return false; } $markTotal = 0; $markGrade = 0; $weightSession = 0; $markGradeSum = 0; $grade = ""; $sessionsHTML = ""; $courseHTML = ""; foreach($sessionData as $session) { $sessionsHTML .= "<p><strong>Session:</strong> {$session['SessionId']} <strong>Session Mark:</strong> {$session['Mark']}</strong> <strong>Session Weight Contribution</strong> {$session['SessionWeight']}%</p>\n"; $markTotal += round($session['Mark'] / 100 * $session['SessionWeight']); $weightSession += ($session['SessionWeight']); $markGrade = round($markTotal / $weightSession * 100); $markGradeSum = round($markGrade); if ($markGrade >= 70){ $grade = "A";} else if ($markGrade >= 60 && $markGrade <= 69){ $grade = "B";} else if ($markGrade >= 50 && $markGrade <= 59){ $grade = "C";} else if ($markGrade >= 40 && $markGrade <= 49){ $grade = "D";} else if ($markGrade >= 30 && $markGrade <= 39){ $grade = "E";} else if ($markGrade >= 0 && $markGrade <= 29){ $grade = "F";} } $moduleHTML = "<p><br><strong>Module:</strong> {$moduleID} - {$moduleName} <strong>Module Mark:</strong> {$markTotal} <strong>Mark Percentage:</strong> {$markGrade} <strong>Grade:</strong> {$grade} </p>\n"; return $moduleHTML . $sessionsHTML; } $output = ""; $studentId = false; $courseId = false; $moduleId = false; while ($row = mysql_fetch_array($result)) { if($studentId != $row['StudentUsername']) { //Student has changed $studentId = $row['StudentUsername']; $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n"; } if($courseId != $row['CourseId']) { //Course has changed $courseId = $row['CourseId']; $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong> <strong>Grade</strong> <br><strong>Year:</strong> {$row['Year'] $markGradeSum}</p>\n"; } if($moduleId != $row['ModuleId']) { //Module has changed if(isset($sessionsAry)) //Don't run function for first record { //Get output for last module and sessions $output .= outputModule($moduleId, $moduleName, $sessionsAry); } //Reset sessions data array and Set values for new module $sessionsAry = array(); $moduleId = $row['ModuleId']; $moduleName = $row['ModuleName']; } //Add session data to array for current module $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']); } //Get output for last module $output .= outputModule($moduleId, $moduleName, $sessionsAry); //Display the output echo $output; } } ?> How can I retrieve the variable so it doesn't come up with the notice but be able to display $markGradeSum to the places I want them in (one in foreach loop for calculation and other in while loop for output). Thank You Hello, I have a booking system which has time and date fields and if someone tries to book, for example, on 01/01/2011 at 09:00, when this slot is already taken, an error would be produced - which is fine. However I'm not sure in telling them what hours are available. There are 9 available times: 09,10,11,12,13,14,15,16,17:00. I will need to perform an sql query to gather all the times on the inputted date, I'm guessing a for loop would be the most efficient way? The only way I could think of is using multiple IF queries, for example: Code: [Select] <?php $sql = "SELECT `Hour` FROM `jobs` WHERE `Hour` = '09:00:00' AND Day ='$Day' AND Month ='$Month' AND Year ='$Year'"; $result = mysql_query($sql); if(mysql_num_rows($result) > 0){ $09Available = 'n'; // Time not available }else{ $09Available = 'y'; } $sql = "SELECT `Hour` FROM `jobs` WHERE `Hour` = '10:00:00' AND Day ='$Day' AND Month ='$Month' AND Year ='$Year'"; $result = mysql_query($sql); if(mysql_num_rows($result) > 0){ $10Available = 'n'; // Time not available }else{ $10Available = 'y'; } $sql = "SELECT `Hour` FROM `jobs` WHERE `Hour` = '11:00:00' AND Day ='$Day' AND Month ='$Month' AND Year ='$Year'"; $result = mysql_query($sql); if(mysql_num_rows($result) > 0){ $11Available = 'n'; // Time not available }else{ $11Available = 'y'; } ?> etc. etc.. How would I go about creating a more efficient method? Thank you, Jack. I have a form that ask user to enter other details but the primary key as this is automated and when they click on Submit button it takes the user to different form. now on this form I would like to retreive the primary that has just been added to the table.

I've been running a self-written php shopping cart for the last 8 years, with lots of success. Recently however, the credit card processor (Linkpoint) I use upgraded their gateway, and now I have a problem.
Basically, the last page of my checkout does a _POST to a specific url for their gateway. I send through a bunch of <input> variables, some of them hidden, but all of them check out okay. I have combed over their specs, made sure I'm not sending any bad characters, made sure I've got the right format for the fields they want, etc...
Right now the transaction is successful, the customer's card is charged, but Linkpoint's system is returning an error message: We are unable to process your request due to invalid data.
Long story short, their support staff has asked me to "send them the xml string" via email. I have no idea how to do this (even after spending a few hours online trying to figure it out).
Is there a simple way to generate the xml string that's being passed during the _POST? Some kind of php code I can incorporate into my final checkout page, run a test transaction, and maybe write the string out somewhere so I can get it to them?
Any help you guys could give me would be greatly appreciated. Thanks in advance! Danny I have a form where you can pick all the days in the week. When the form is posted my code finds the date of the day you picked that most recently went by. Then the code takes that date, and echos the date of every day of the week that you picked that comes after that date for a year. But for some reason he thinks we're in 2009, even though i know the date puts out that we're in 2010. Here's the code: <?php //function if(isset($_POST['submit'])) { function nextWeeksDay($date_begin,$nbrweek) { $nextweek=array(); for($i = 1; $i <= $nbrweek; $i++) { // 52 week in one year of course $nextweek[$i]=date('d-m-y', strtotime('+'.$i.' week',$date_begin)); } return $nextweek; } //Get what user posted as day, and find the date of the past day gone. $roday = $_POST['day']; echo $roday; echo date('d-m-y',strtotime('last ' . $roday)); $sistdag = date('d-m-y',strtotime('last ' . $roday)); /// end function /// example of a select date // var $date_begin = strtotime($sistdag); //D Day Month Year - like function format. $nbrweek=52; // call function $result=nextWeeksDay($date_begin,$nbrweek); // Preview for($i = 1; $i <= $nbrweek; $i++) { echo '<br> - '.$result[$i]; } } ?> All help appreciated! |
