PHP - Looping Make_seed Function In A Foreach
Im trying to assign and update table rows with a random 9 character string but am receiving the error : Fatal error: Cannot redeclare make_seed() (previously declared in ...
How can I clear/reset the value before the next loop Code: [Select] else { while ($data=mysql_fetch_array($users)){ $user=$data[user]; $usersarray = array($users); foreach ($usersarray as $key => $u){ //clear pass $token = ""; srand(); //generate new password $password_length = 9; function make_seed() { list($usec, $sec) = explode(' ', microtime()); return (float) $sec + ((float) $usec * 100000); } srand(make_seed()); $alfa = "1234567890qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM!@#$%^&*(){}[]"; for($i = 0; $i < $password_length; $i ++) { $token .= $alfa[rand(0, strlen($alfa))]; } // insert password // setup SQL statement $SQL = " UPDATE data SET pass='$token' WHERE user='$m1' "; // execute SQL statement $makeit = mysql_db_query($userdb,"$SQL",$usercid); // check for error if (!$makeit) { echo("ERROR: " . mysql_error() . "\n$SQL\n"); } Similar TutorialsI'm trying to figure out what I'm doing wrong. For each recipient it runs each value which is an integer through the getUserByUserID function to verify that no values inside of the array are non users. But here's the part I'm not sure of and that's the if $recipient or $sender == FALSE. If ANY of the values are found to be non values then I want that if statement to activate. Code: [Select] foreach ($this->input->post('recipient[]') AS $recipient) { $this->users->getUserByUserID($recipient); } $sender = $this->users->getUserByUserID($this->input->post('sender')); // Verifies users were returned from database if (($recipient == FALSE) || ($sender == FALSE)) { // Users was not found in the database $outputArray['message'] = 'Either the recipient or yourself could not be found in the database!'; } hi there. i have a class that queries my db, creates an array objects representing a collection of the items returned. when i pass the array back to the caller and then try to loop through the array, it keeps displaying the same record - i think it's the last record that is displayed however, when i try the same code in the class, it prints out each unique record. i tried doing a reset(myarray); on the caller but that dind't work either. any suggestions? here's the code to loop through the array: if ( count( $myarray ) > 0 ) { //reset($lineItem_array); foreach ( $myarray as $lineitem ) { echo($lineitem->getName()."~"); echo($lineItem->getOId()."~"); echo($lineItem->getProduct()."~"); echo($lineItem->getPIP()."~"); echo($lineItem->getQuantity()."~"); } } } } Is there a nicer, cleaner more efficient and less code way of achieving this?
I have an array of rows from the database and 2 of the columns could have either of 2 values which give me 4 possibilities.
I want to loop through each of them and assign the row to one of 4 arrays so they are all separated out.
This is what i have so far. Haven't tested it yet but the theory makes sense.
if(!empty($rows)) {
foreach($rows as $key => $row) {
switch($row['type']) {
case 'post':
switch($row['archived']) {
case 0:
$array1[$key] = $row;
break;
case 1:
$array2[$key] = $row;
break;
default:
}
break;
case 'event':
switch($row['archived']) {
case 0:
$array3[$key] = $row;
break;
case 1:
$array4[$key] = $row;
break;
default:
}
break;
default:
}
}
}
Hi Guys I have never reall worked with xml and im stuck.

Can anyone please help with this. Thanks $array = array("1","2","3"); foreach ($array as $value){ echo $value; } Put its only echoing out 3, not the whole array. Hello all.. This one's sort of difficult to explain, but yet it should be a pretty simple solution.. What I'm trying to do is loop through an array that has either single event id's or a group of event id's, and run a condition on the change of id's while looping.. Sort of grouping each set if unique id's within a new event section.. Here's sort of a test code I put together: Code: [Select] <?php $result = array( array('event_id' => 70), array('event_id' => 70), array('event_id' => 70), array('event_id' => 95), array('event_id' => 96), array('event_id' => 97), array('event_id' => 98), array('event_id' => 99), array('event_id' => 145), array('event_id' => 145), array('event_id' => 145), array('event_id' => 145), array('event_id' => 166), array('event_id' => 166), array('event_id' => 177), array('event_id' => 200), array('event_id' => 200), array('event_id' => 200) ); $previous_id = ''; foreach($result as $row){ if ($row['event_id'] != $previous_id) { echo '<div style="background:#ccc;">New Event</div>'; } if ($previous_id > 0 && $row['event_id'] != $previous_id) { echo '<table border="1"><tr><td>'.$row['event_id'].'</td></tr></table>'; $previous_id = ''; } else { echo $row['event_id'].'<br />'; $previous_id = $row['event_id']; } } ?> It's about half way working, but there are issues when the ids change and they are either single event ids in a row, or multiple same event ids in a row.. I can't think how to set the $previous_id variable properly on each loop.. Well, figured I'd throw it out there and see what happens.. Thanks..

I've made this code for a very simple registration form practice:
//assign form variables
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$username = $_POST['username'];
function clean_names($dirty_name) {
strip_tags($dirty_name);
str_replace(' ', '', $dirty_name);
ucfirst(strtolower($dirty_name));
//return $dirty_name;
}
$names = array($firstname, $lastname, $username);
if(isset($_POST['register_button'])) {
// WHY IS THIS FUNC CALL NOT WORKING??
foreach($names as $name) {
clean_names($name);
}
echo "First Name: " . $firstname . "<br>";
echo "Last Name: " . $lastname . "<br>";
echo "Username: " . $username . "<br>";
}
The values are returned but they haven't been put through the clean_names function. Hello, I am new to PHP and have come to a grinding halt in my project. I am attempting to dynamically generate values for Wordpress shortcodes ( [example] ). I have successfully created the shortcodes and am having trouble setting their value. When I call the function that is supposed to return the value for the shortcode, it returns empty. I can however hard code a string and have it returned to the function, thereby manually creating a value for the shortcode. However, because the shortcodes are being generated and filled dynamically, I need this function to work without specific values. I know this may sound like a Wordpress specific question, but I have a feeling it's just my lack of understanding of PHP operations. So, here is the basic layout: The name of the shortcode is generated from within a foreach loop that retrieves the name of custom fields on the post ($keyName). Code: [Select] $custom_field_keys = get_post_custom_keys(); foreach ( $custom_field_keys as $key => $keyName ) { $valuet = trim($keyName); if ( '_' == $valuet{0} ) continue; if ( get_post_meta($thePostID, $keyName, true) ) : $fieldName = get_post_meta($thePostID, $keyName, true); endif; $fieldValue = $_GET["$keyName"]; add_shortcode((string)$keyName, 'myFields'); } The add_shortcode function has two parameters ('name_of_shortcode', 'function_name'): Code: [Select] add_shortcode((string)$keyName, 'myFields'); I need the myFields function to return the value of $fieldValue from within the foreach loop. That's where the problem lies. This doesn't work: Code: [Select] function myFields() { $myString = preg_replace('/[^a-zA-Z\s]/', '', $fieldValue); return $myString; } This does work: Code: [Select] function myFields() { return 'Content to replace the shortcode'; } This code will replace [shortcode] with "Content to replace the shortcode" in the post. The ultimate goal is: when [$keyName] appears anywhere within the post, it will display the content returned by the myFields function ($fieldValue). However, it's not working. I can't seem to pass the value of $fieldValue to the myFields function and thereby return it to add_shortcode. Any help is appreciated and I am awaiting anxiously to answer any questions. Here's all the code together: Code: [Select] function myFields() { $myString = preg_replace('/[^a-zA-Z\s]/', '', $fieldValue); return $myString; } $custom_field_keys = get_post_custom_keys(); foreach ( $custom_field_keys as $key => $keyName ) { $valuet = trim($keyName); if ( '_' == $valuet{0} ) continue; if ( get_post_meta($thePostID, $keyName, true) ) : $fieldName = get_post_meta($thePostID, $keyName, true); endif; $fieldValue = $_GET["$keyName"]; add_shortcode((string)$keyName, 'yourFunction'); } Can anyone help me complete this script I can get it working with using an implode function, but for the purpose of knowledge I want to not use it. I just want it to echo back the corresponding checkboxes, but I can't get the echoing correct, it echoes back array not the value? Code: [Select] <html> <title>What do you want on your Tombstone?</title> <body> <?php $Output_form = true; if (isset($_POST['submit'])) { if (empty($_POST['toppings'])) { echo '<b>You forgot the toppings for your Tombstone.</b>'; echo '<br>'; echo '<br>'; } else { echo '<p><b>This is what you are getting on your Tombstone: '; (array)$_POST['toppings']; echo $toppings; echo '!'; echo '</p></b>'; $Output_form = false; } } if ($Output_form) { ?> <form action="ProcessToppings.php" method="post"> <p><i><h2>What do you want on your Tombstone?</h2></i></p> <p> <input type="checkbox" name="toppings[]" value="pepperoni" /> Pepperoni<br /> <input type="checkbox" name="toppings[]" value="sausage" /> Sausage<br /> <input type="checkbox" name="toppings[]" value="mushrooms" /> Mushrooms<br /> <input type="checkbox" name="toppings[]" value="cheese" /> Cheese<br /> <input type="checkbox" name="toppings[]" value="olives" /> Olives</p> <p> <input type="submit" value="Make that Peet-Za!" name="submit" /></p> </form> <?php } ?> </body> </html> hey guys, I'm quite new to PHP and i was wondering if someone would be able to help me out with this. The code i have checks the database to see if a user has provided a Vimeo ID. If they haven't, $video_check will equal a line of html that says the user hasn't added any videos to their portfolio. If the a vimeo ID is present, i want $video_check to equal a bunch of html and css with a foreach function inside that is used to display the users videos from vimeo. The foreach function works fine when its not assigned to the $video_check variable. How do i structure it so that it displays correctly? If you click on videos on this page you might get a better idea of what i'm talking about. http://www.myfilmportfolio.ie/profile.php?id=33 and here is the code i'm having the problem with: /////// check if user has provided vimeo id ////////////////////////// $vimeoID = $row["vimeoID"]; $video_check=''; if (empty($vimeoID)){ $video_check = '<h3>'.$firstname .' has not added any videos to their portfolio</h3>'; } else{ $video_check = '<div id="stats"> <div style="clear: both;"></div> </div> <div id="wrapper"> <div id="embed"></div> <div id="thumbs"> <ul> <?php foreach ($videos->video as $video): ?> <li> <h4><?=$video->title?></h4> <a href="<?php echo $video->url ?>"> <img src="<?php echo $video->thumbnail_medium ?>" class="thumb" /></a> <p><?=$video->description?></p> <br /> </li> <?php endforeach ?> </ul> </div> </div>'; } if anyone could help me out id really appreciate it. Cheers, G This topic has been moved to Application Frameworks. http://www.phpfreaks.com/forums/index.php?topic=355772.0 I'm not sure if the title explains it very well, but here is an image of it. I am trying to figure out how to access the option selected (equal, not equal, etc.), along with its input box, for each column (the checkboxes on the right) selected. The purpose of this is to allow a non-programming administrator user to create a custom query to access information. I can find out which checkboxes are selected no problem, but finding the accompanying drop-down option and input box is difficult for me. How do I do this?

If you take a look, it has a node titled "Question". With PHP, how can I loop through each "Question" node and grab all of it's children as well? I tried this code, but apparently it did not work: $req = "http://answers.yahooapis.com/AnswersService/V1/questionSearch?appid=YahooDemo&query=php"; $res = file_get_contents($req); $xml = simplexml_load_string($res); foreach ($xml->xpath('//Question') as $question) { // "//question" means for each question node echo((string)$question['Subject']." - ".(string)$question['Content']); // you get all the child nodes in $question } Hey, I have the following code that gets the name of the course from the XML. XML Snippet Code: [Select] <?xml version="1.0"?> <courses> <course> <id>70</id> <name>Marketing and Social Media</name> <dates> <date> <instance_id>6747</instance_id> <location /> <course_type>Day</course_type> <date_available>2011/07/13</date_available> <time_start>9:30</time_start> <time_end>17:00</time_end> <availibility>7</availibility> <running_dates> <running_date>2011/07/13</running_date> <running_date>2011/07/14</running_date> </running_dates> </date> </dates> </course> <course> </courses> PHP Code: [Select] $dom = new DomDocument(); $dom->load("courses.xml"); $xp = new domxpath($dom); $titles = $xp->query("/courses/course/name"); foreach ($titles as $node) { print $node->textContent . " "; } This prints out the course name fine. My question is how Can i get the rest of the data from the same query. For example why cant I do something like.. Code: [Select] ... foreach ($titles as $node) { print $node->name. " "; print $node->time_start. " "; print $node->course_type. " "; etc.. } So I want to loop through get the name and assign the rest of the nodes in there to variables or something. |
