PHP - How To Use One Array To Display Items From A Second Array
Hi,
I'm hoping someone can help me with a simply array problem. I have a table with two columns: "ID" and "Name" and 100 Names. I also have an array called $myIDList containing 10 IDs. I want to display 10 Names from the table that correspond with the IDs from my array. Originally, I tried to implode the array, adding commas and inserted into my MySQL query using: $myQuery = "SELECT ID, Name FROM namesTable WHERE ID IN ($myImplodedIDList)"; The problem was that duplicated names (i.e. the same Name, but assiged to different IDs) would only be displayed once. So now I'm trying to use the original array to loop through a second array and display Names where the ID matches an ID from my first array. I have succesffuly listed the table like this: $myQuery = "SELECT ID, Name FROM myTable ORDER BY ID"; $myResult = mysql_query($myQuery) or die(mysql_error()); while($row=mysql_fetch_array($myResult)) { echo $row['ID']; echo $row['Name']; } But I want to do something like: while($row=mysql_fetch_array($myResult)) { while $row['ID'] = $myIDList { echo $row['Name'] } } Can someone shed some light onto this for me please? Thank you! Bryan Similar TutorialsHello all, I need to make a rotating banner system for a client. They want about 5 banners to rotate with Javascript. However they want the visitor to sort of step through each one on each refresh. So if I have 5 banners and I go to the site, I see banner 1 and then the javascript rotates through each one. When I go back to the site, they want it to start with banner 2 and then the javascript will rotate through each one. Then on and on. Go back and see banner 3, then step through again. I have a nice Javascript image slider I'd like to use. It basically just requires the images in order. Like: <img src="1.jpg"/> <img src="2.jpg"/> <img src="3.jpg"/> <img src="4.jpg"/> <img src="5.jpg"/> I've thought about it and I think the best way to do this would just be using PHP and a cookie. So when the viewer first goes to the site, PHP checks for the cookie. If it exists, it pulls the starting image #. If it doesn't, it starts at 0 and sets the cookie. As for the images part, I figured an associate array would work well. The key would be what the cookie logic is based on, and then the image HTML would be in the array. So you visit the site without a cookie it would be... 0 => <img src="1.jpg"/> 1 => <img src="2.jpg"/> 2 => <img src="3.jpg"/> 3 => <img src="4.jpg"/> 4 => <img src="5.jpg"/> Then when you go back to the site, I need the array to be re-ordered like this: 0 => <img src="2.jpg"/> 1 => <img src="3.jpg"/> 2 => <img src="4.jpg"/> 3 => <img src="5.jpg"/> 4 => <img src="1.jpg"/> What's the best way to go about this array logic? My experience with manipulating data inside arrays is rather limited. Basically I need it to say "Start with key # and then reorder array based on that" I have an array of products. The array has an ID and price. I'd like to know the most efficient way of adding up all the same ID fields in the array. Code: [Select] <?php $items[] = array( 'id' => 1, 'price' => 5.99, ); $items[] = array( 'id' => 2, 'price' => 1.99, ); $items[] = array( 'id' => 3, 'price' => 2.40, ); $items[] = array( 'id' => 2, 'price' => 6.99, ); $items[] = array( 'id' => 4, 'price' => 8, ); $items[] = array( 'id' => 2, 'price' => 3, ); $items[] = array( 'id' => 3, 'price' => 1, ); function add_like_items($items) { //manipulation return $sums; } //$sums would be an array like //$sum[1] = 5.99 //$sum[2] = 11.98 //$sum[3] = 3.40 //$sum[4] = 8 ?> Anybody have suggestions on the best way to go about doing this? How can I check if an array contains two items that are the same? For example ("apples", "bananas", "oranges") returns false But ("apples", "bananas", "bananas") returns true Hi, Im wondering if there is an easy way to get items out of an array returned by a function inside a class. A code example would be: Code: [Select] class modDB { public function getPwdSalt() { $arr = array("salt", "password"); return $arr; } } ?> And what i would like to be able to do is something like: Code: [Select] $modDB = new modDB; echo $modDB->getPwdSalt()->[1]; and just get returned 'password'. Is something like that possible? Many Thanks. Running a simple query: SELECT team, rank from table ORDER BY rank ASC returns 8 records in order from 1 to 8 I then want to a assign a new variable to each that I can use for later queries ie: team with rank 1 = $team1 team with rank 2 = $team2 team with rank 3 = $team3 etc.... Thanks in advance. Hi all, I have a table that shows data from an xml response that has been converted to an array. I have successfully managed to get that to work but it's showing more items than I want. I'm trying to isolate the items by state. There are 11 or so different states, of which I only want 7. I've tried the following with a while loop but I keep getting the message "undefined index: job_status" Here's my code (partial)
$projects = array();
$xml=simplexml_load_string($response) or die("Error: Cannot create object");
foreach($xml->Jobs->Job as $item) {
$projects[] = array(
'job_no' => (string)$item->ID,
'job_name' => (string)$item->Name,
'job_due' => (string)$item->DueDate,
'job_status' => (string)$item->State,
'job_staff' => (string)$item->Assigned->Staff->Name,
);
}
usort($projects, function($a,$b) {return $a['job_due'] <=> $b['job_due']; } );
$projects = array_reverse($projects);
while ($projects['job_status'] == ('Feasibility')
&& ('Measure Up')
&& ('Model Drawing')
&& ('Concept Design')
&& ('Developed Design')
&& ('Resource Consent')
&& ('Construction Documentation')) {
foreach ($projects as $proj) {
$formatted = date('d/m/Y', strtotime($proj['job_due']));
$job_no ="{$proj['job_no']}";
$job_name ="{$proj['job_name']}";
$job_due ="$formatted";
$job_status ="{$proj['job_status']}";
$job_staff ="{$proj['job_staff']}";
Any help would be much appreciated thanks. Hi guys, I'm just working on a script to get menu items from a database, sorted by a sort column. Each item needs to be checked to see if it has a parent, then paired with the parent. Would it be best to get all of the items at once and pair them with PHP, or get the children of each item when as a separate array? id label link parent sort 1 Home index.php 0 10 2 About about.php 0 20 3 Contact Us contact.php 2 10 -First I want to say that I love this site and always check google before I submit questions but im lost. I'm into security and trying to learn a little Apache, Mysql, and PHP to understand the development cycle better. As practice im creating a notecard test review site. Create notecard Decks, add/delete questions etc. shuffle, then test yourself. I though I was doing good until I got to the page that shows the questions (test.php). Right now I pass the "deck_id" field in a GET to a "test.php?id=" page that runs a script that pulls out all the questions for that deck from my "questions" table and loops to show each question for that "deck". My loop works, (gets array from database and shows questions one by one), but it writes all the questions to the page at the same time. DUH. I want it to show one question with a "NEXT" button to show next question. This button clears the first question and writes the next one until they are all done. No grading or anything needed. Is there a way to do this gracefully? I dont know much javascript but looked up innerHTML and see i can update text that way but the PHP loop I have goes so fast it just end up showing the last question with no way to pause it between questions. Can anyone think of a way to do this? My problem is passing the data from page to page to page (I lose the array data) If this is impossible my other thoughts a 1) store current list of Q/A's in cookie (OR) 2) pass Q/A to another page with POSTS (OR) 3)store Q/A's to temporary sql table and use GETS in loop to show each one by one. "testing.php?question=1" 4) can i set a global variable that can pass the data to separate pages? 5)user iFrame so it looks like one page (dont know how) Im leaning to number 3 but want to hear your suggestions. (sorry very new) Quote from: Hollows on August 20, 2010, 11:29:25 AM I have an array that is pulling 10 results from a db like this - <?php $result = mysql_query("SELECT * FROM inbox ORDER BY id DESC LIMIT 0,10"); while ($row = mysql_fetch_array($result)) { <div class="<?php echo $row['class']; ?>"> <?php echo $row['name']; echo $row['message']; ?> </div> basically 'class' is defined in an earlyier part of the script and is used to tell the css what class to display - as I'm sure you can see. What I'd like todo then be able to update the class of a message once I have read it, so update the class table with something like 'read' so the css will then be based on .read not what ever was set by the form, either using a link or form button inside each of the 10 results from the array. I've managed to update one by using - Code: [Select] mysql_query("UPDATE shoutbox SET class = 'read' WHERE id = ''XX"); // XX should be row id But I had to set that myself and point the id to the row id I wanted to change - How can I have that already populated with the row for the id that triggered it? To be clear so it looks like - Name Message read button _____________ Name Message read button _____________ Name Message read button _____________ and so on... Would I be better going by check boxes and one submit button? If so how could I implement that? I can provide the full code I've written if it helps Thank you in advance I have this array of items in my php file.

Not being an expert in php, I have somehow managed to reach thus far in my code, but can not quite arrive at the correct logic. Having trouble with handling associative arrays and objects in php.

I have now reached a point where I desperately need help from experts.
When I remove 1 session item using this it works fine when I select more than 1 item to be removed I get unexpected results, I have checked the outputted html to see what positions get echoed into the remove check box and they are correct, so I guess the problem lies in my remove code here is the part of the form that sends the remove check box <?php for ($basket_counter=0;$basket_counter<$_SESSION['ses_basket_items'];$basket_counter++) { $price=sprintf("%01.2f",$ses_basket_price[$basket_counter]); $quantity=$ses_basket_amount[$basket_counter]; $code=$ses_basket_stockcode[$basket_counter]; $itemID=$ses_basket_id[$basket_counter]; $name=$ses_basket_name[$basket_counter]; $image=$ses_basket_image[$basket_counter]; $size=$ses_basket_size[$basket_counter]; $sizechoice=$ses_basket_sizechoice[$basket_counter]; // create array from sizes and make the option box selections if ($sizechoice!="" && (!in_array($sizechoice, array('One Size', 'one size', 'free size', 'Free Size', 'Adjustable', 'adjustable')))) { // add size trigger $sizelist="add"; //create the array $sizepick=explode(",", $sizechoice); } else { $sizepick=$sizechoice; } // adjust gst for AU customers if ($country=='AU') { $price=sprintf("%01.2f",($price*1.1)); $unit=sprintf("%01.2f",($price/$quantity)); } else { $unit=sprintf("%01.2f",($price/$quantity)); } ?> <tr> <td align='center' class='rescon' style="border-bottom:solid #330000 1px;"><input type="checkbox" name="remove[<?php echo $basket_counter; ?>]" value="<?php echo $basket_counter; ?>" /></td> and here is the part of the code that processes the removal of the items $remove = $_POST['remove']; if (isset($remove) && ($remove!='')) { foreach($remove AS $key => $remove_position){ array_splice ($ses_basket_name, $remove_position, 1); array_splice ($ses_basket_amount, $remove_position, 1); array_splice ($ses_basket_price, $remove_position, 1); array_splice ($ses_basket_stockcode, $remove_position, 1); array_splice ($ses_basket_image, $remove_position, 1); array_splice ($ses_basket_size, $remove_position, 1); array_splice ($ses_basket_sizechoice, $remove_position, 1); array_splice ($ses_basket_id, $remove_position, 1); $_SESSION['ses_basket_items']--; } } I am using a form with checkboxes named remove[$remove_position] and the positions in the form are correct for each item in the array, but when I select more than 1 item to delete they are not always the correct items only the first 1 selected. What am I doing wrong here?? I'm new at PHP and have a problem. I have a MySql database with lists of students grouped into classrooms. A typical group is shown in the attached screenshot screenshot.docx. I want to be able to select one or more of the names by using the associated checkbox, and upgrade a student or students into a different group as defined in the radio button list also in the screenshot. I have the rudiments of the file attached, but I have absolutely no idea how I can post the array so that the records are updated. Each student has an individual record with a field name userGroup which holds a string nominated by their classroom teacher, such as "year7", "year 8" and so on while they are in one of the several classrooms, but when they leave school this is recorded in a field named noGroup with a value of 0 or 1. I can post further details as required, but it would be great if someone could help me. Sample array: array('one','two','three','_zero'); How could I sort this array so that _zero moves to the front.. Any items that begin with an underscore should be moved to the front of the array to get something like so: _zero, one, two, three Thanks I have users in my database with many stored points ie age, gender, interests etc. about 20 points in all.
I have a table of products that I want to recommend only applicable products. They each have saved like minage, maxage, gender, interest etc for the ideal consumer. ie dress gender=f
This is the bare bones of what I have so far:
$result = mysql_query("SELECT * FROM user_table WHERE hash='$session_id'");
$rowuser = mysql_fetch_array($result);
$result = mysql_query("SELECT * FROM products");
$rowproducts = mysql_fetch_array($result);
So now I have $rowuser['gender'] = m , how do I remove all from $rowproducts where gender = f?
Is there a best way to do this knowing I have about 20 points to go through before I am left with an array with just the best selection of products for this user in it?
Hi, Is it possible to display the whole array of voteID in this url? https://falling-skies-tv.loopiasecure.com/vote_result.php?voteID=292&comp=falling-skies-danmark Is there a script/website/code I can use? Thank you! $color=array("01 orange","02 blue","03 red"); If my array was structured this way where the first two characters represented a code, how would I be able to display the code and color distinctly? my user pm table has a touserarray field which is a serialized array that looks like this: a:1:{s:2:"cc";a:1:{i:15773;s:14:"testusername";}} i know I can unserialize it with the unserialize() function. But I need to extract the value corresponding to 'i' field and the 's' field that has the username. So from the above array, i need to retrieve the value '15773' and 'testusername'. Can someone tell me how? I've been trying to get this to work for a few days now and can't seem to get anywhere with it! Any help is very much appreciated. I am creating a number generator where the user is required to insert the maximum number and generate rate. Maximum number is the highest number that the script will go to, and generate rate is how many numbers should be created. When the script runs, the numbers are stored into a MySQL database. The MySQL database creates a unique ID number so it can be recalled at a later date. The user then needs to go to Sorting.php and selects the record they wish to use. The numbers from this record are then counted and then stored into an array. If the numbers 2,5,5,0,2,2,1,3,5,1 where generated, the output of this new array will be: [5] => 3 [3] => 1 [2] => 3 [1] => 2 => 1 (These arrays can be of any length) I now need to extract this data and show it on screen. I don't know how to approach it. Format example: Number 5 appears 3 times Number 3 appears 1 times Number 2 appears 3 times Number 0 appears 1 times Sorting.php <?php $db1 = new Number_Information(); $db1->openDB(); $sql = "select * from GeneratedNumber"; $result = $db1->getResult($sql); if (!$_POST) { //page loads for the first time ?> <form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="post"> Select the ID (If you have just generated a number, it will be the last one): <!--This is the drop down menu--> <select name="ID"> <?php while ($row = mysql_fetch_assoc($result)) { echo "<option value='{$row['ID']}'> {$row['ID']} </option>"; } ?> </select> <br /> <input type="submit" value="Continue" /> </form> <?php } else { $ID = $_POST['ID']; //This will contain the value that was selected in the drop down menu above. $result = mysql_query("SELECT NUMBERS2 FROM GeneratedNumber WHERE ID='{$ID}'"); //This tells the script to select NUMBERS2 contents which is assosiated with the ID. while ($row = mysql_fetch_array($result)) $NUMBERS2 = $row['NUMBERS2']; echo "$NUMBERS2"; //Testing reasons - remove it later. echo "<br />"; //same as above echo "$ID"; // as above. echo "<br />"; //as above //Convert NUMBERS2 back into an array when inserted into table from Generator.php $NUMBERS = explode(",", $NUMBERS2); // Counts how many times a number appears //******************************************************************************************************************* //IF ALL ELSE FAILS, REVERT BACK TO THIS. //print_r(array_count_values($NUMBERS)); //It will only print the statement, but gives you a good building block when things WILL go wrong. //******************************************************************************************************************* rsort($NUMBERS); print_r(array_count_values($NUMBERS)); (The questions when editing posts are hard. I've needed to Google both of them:() I have the following code that queries the database for the results of a quiz. The display reports on completed quizzes, showing, line by line, the quiz title, the date of the quiz, an image of a green tick if the quiz result was correct or an image of a red cross for an incorrect result and a fractional result shoratio of correct answers. A student can repeat a quiz numerous times, and therefore his results for a particulat quiz can display several rows with green ticks and red crosses for the same test done at different times with differing results. I want to recode this so that the red crosses for incorrect results will no longer display once a student achieves a green tick result. I've had several goes at this but my results are less than encouraging. Can anyone help? Do I tackle this through an altered query, or should I include conditions in the display of the array? Code: [Select] <?php $query1 = mysql_query("SELECT DISTINCT quizTitle, userId, passState, userScore, totalScore, DATE_FORMAT(userDate,'%b %e, %Y') AS userDate FROM quiz WHERE managerId = '$managerId' AND userId = '$userId' ORDER BY quizTitle, userDate ASC"); while ($row = mysql_fetch_array($query1)) { echo "{$row['quizTitle']} <br />\n"; echo "{$row['userDate']} <br />\n"; if ("{$row['passState']}" == 1) {echo "<img src=' ../../wood/wood_tool_images/tick2.png' /><br />\n";} if ("{$row['passState']}" == 0) {echo "<img src=' ../../wood/wood_tool_images/cross2.png' /><br />\n";} echo "{$row['userScore']}".'/'."{$row['totalScore']} ?> |
