PHP - Confusing Loop, Need Help
Ok, so first off, here is how the tables are setup:
Cars_Table | ID, CatID Categories_Table | ID, Parent_ID, Name Now, both parent categories and sub-categories are in the same table. the C_Table.CatID shows only the sub-category the item is in. How would I make a list of the distinct names of Parent category names (those with Parent_ID = 0) in ASC order, but I want to only pull the parent categories for which there is an item associated. Essentially, the makes and models of the cars are stored in the same table, the Makes are the ones with Parent_ID = 0 and the Models also have parent ID's. The Cars_Table.CatID only shows the Model ID. I'm still fairly new to PHP and this one is really confusing me O.o Similar TutorialsI was wondering if you loop through an array and in the foreach() you specify an if statement that unsets certain items from the array, if those get unset from the original loop. Probably doesn't make much sense so heres an example Code: [Select] <?php //say there are 3 items in the $parent array //say there are 10 items in the $items array //say only the second item in the $items array value_one equals "abcd" foreach($parent as $id => $value) { foreach($items as $key => $value) { if($items[$key]['value_one'] == "abcd") { unset($items[$key]); } } } ?> So on the first item in the parent array, all 10 items would be cycled through. On the second second item of the parent array, all 10 items would be cycled through and the one item that has value_one == "abcd" would be unset. So on the third item of the parent array, am i correct in assuming only 9 items would be cycled through because there would be only 9 items in the $items array? Everytime I test my page, I seem to get a parse error, in which I have tried to identify the problem but I am stumped as to what it is. This is the error... Code: (error) [Select] Parse error: syntax error, unexpected '}' in C:\xampp\htdocs\drew\film.php on line 21 The php code (lines 21-24 relevant to the error) are below... <?php if($flm == "73d0" || $flm == "9017" || $flm == "c3a2") {$pass = 1}else {$pass = 2} ?> <?php if ($pass != 1) { ?><meta http-equiv="refresh" content="0;url=/drew/"><?php }else { ?> <?php echo "hello"; } ?> If you could help, thanks in advance. I created a new homepage for my network of sites I run. I tried to go for a simple and clean look. The pages themselves function how I'd like, but I'm unsure if the menu system is easy to understand or not.
I even added a time limited message on the front page of the site indicating that the logo was clickable, but purposely left it off of other sub-pages to try and keep the design as clean as possible.

Rules: 1) It has to be legit and actually work and have a useful function in society/web world. 2) The code cannot be minimized into one line. It has to have line breaks. (Not necessarily for each new function or short hand property, but so it's partly readable) 3) It has to be written in PHP or Javascript. For example, (Not my original code) but I'll start: A time_ago function: function timeago($tm,$rcs = 0) { $cur_tm = time(); $dif = $cur_tm-$tm; $pds = array('second','minute','hour','day','week','month','year','decade'); $lngh = array(1,60,3600,86400,604800,2630880,31570560,315705600); for($v = sizeof($lngh)-1; ($v >= 0)&&(($no = $dif/$lngh[$v])<=1); $v--); if($v < 0) $v = 0; $_tm = $cur_tm-($dif%$lngh[$v]); $no = floor($no); if($no <> 1) $pds[$v] .='s'; $x = sprintf("%d %s ",$no,$pds[$v]); if(($rcs == 1)&&($v >= 1)&&(($cur_tm-$_tm) > 0)) $x .= time_ago($_tm); return $x; }Your turn! Edited by Monkuar, 24 January 2015 - 05:06 PM. Hi, I'm just trying out some basic code and playing around with passing variables by reference and i was reading this on the php manual at this page http://php.net/manual/en/language.references.pass.php : No other expressions should be passed by reference, as the result is undefined. For example, the following examples of passing by reference are invalid: <?php function foo(&$var) { $var++; } function bar() // Note the missing & { $a = 5; return $a; } foo(bar()); // Produces fatal error since PHP 5.0.5 foo($a = 5); // Expression, not variable foo(5); // Produces fatal error ?> So, i decided to try it out myself like i always do, and i noticed that i'm not getting an error when i do foo(bar()); i.e calling bar() without the & in the function declaration. Infact it works perfectly fine and returns an incremented $a after its passed to foo(). Likewise foo($a = 5); also works great and returns an incremented $a after being passed to foo(). Is this a mistake in the manual or am i missing something? Running PHP 5.3.2-1ubuntu4.5 Alright, wasn't quite sure how to summarize this in the title, but I want to: Check if a user status is "active" or not based on the UserName input. I have a table witch holds: Code: [Select] VarChar Username Var CharPassWord int Active Ted TedsPW 1 something like the above(assuming it formatted correctly. In my php script I will want to input a variable for Username to check for: inputUN in this example would be "Ted". $UserNameToCheck = $_GET['inputUN']; Then I want to check for that UserName in the database, if it exists, I want pull the value for the "Active" field for just that UserName and echo it. Thanks for any help. Hey.
So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:
$firstArray = array( 'row1' => array( 'dates' => array( '2014-01-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-02' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-03' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-04' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-05' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-06' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-07' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), ) ), 'row2' => array( 'dates' => array( '2014-02-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-02' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-03' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-04' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-05' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-06' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-07' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-08' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-09' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), ) ) );Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each. And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it.. $placeDataHere = array(); foreach($firstArray as $key => $dates) { foreach($dates as $date => $values) { foreach($values as $key => $value) { $placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value; //Followed by another ~50-70 lines of processing the 3 loop's data.. ... ... .... .... .... .... .... .... } } }Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested. This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance. In short my question is, are there any better methods of handling this with the data setup we currently have? Below is my output on the browser: Student: Kevin Smith (u0867587) Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade Year: 3 Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B Session: AAB Session Mark: 72 Session Weight Contribution 20% Session: AAE Session Mark: 67 Session Weight Contribution 40% Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B Session: AAD Session Mark: 61 Session Weight Contribution 50% Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this. Below is the code: Code: [Select] $sessionMark = 0; $sessionWeight = 0; $courseMark = 0; $output = ""; $studentId = false; $courseId = false; $moduleId = false; while ($row = mysql_fetch_array($result)) { $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']); $sessionWeight += ($row['SessionWeight']); $courseMark = ($sessionMark / $sessionWeight * 100); if($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']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n"; } if($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 $output; I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72? Hey guys, Got another question im hoping someone can help me with. I have a foreach loop (for use in a mysql query): foreach ($interests as $interest) { $query .= "($id, $interest), "; } problem is i do not want the comma(,) in the last loop. Is there some kinda of function i can use so it does not insert it on last loop? Or should i just use a for loop with a nested if loop? something like ; for($i=0; $i < count($interests); $i++){ $query .= "($id, '$interests[$i]')"; if($i + 1 < count($interests)) { $query .= ", "; } } Cheers guys I am working to echo the results in a while or for loop...

In fact 2 questions about that. 1) In the FOR loop I have for example to do the loop 3 times. (needs to find 3 results withing the loop with if and else) When first time, he's gonna search within the WHILE loop that holds (for example) 10 records of the DB in a variable. He needs to search for rowid number 5, he found it He goes out of the WHILE loop and goes searching again but now for rowid number 2 Now it seem that the WHILE loop start searching for number 2 but won't start from his first row in the variable (10 rows from the db ). He start at row number 6 instead of beginning all over again !!! -> so the order of the numbers of rows MUST be in an ascending order, ortherwise he won't find them all ! But the numbers I have are NOT in an ascending order !!! Why doesn't the WHILE loop begin again from his row 1 in the variable ? FOR loop { WHILE loop { content here, break; } } 2) even when I get all the result in an ascending order, he won't go doing a second search but with a different rowid number that he gets from the FOR loop. It is giving me back indeed the right new rowid number, but the WHILE loop is doing nothing. I have put many echo "..."; and other stuff for checking but can't find the cause ! Here's the code : Code: [Select] // $ResultShow = 10 rows from mysql db if(isset($ResultShow)){ if (mysql_num_rows($ResultShow) >= 1){ //$linksuborder = "2,3,4"; $array1 = explode(",", $linksuborder); sort($array1); for ($n = 0; $n < count($array1); $n++){ // searchin for the right row id in the variable $ResultShow where we find the numbers for next loop $r1 = each($array1); While($Row2 = mysql_fetch_array($ResultShow)) { if($Row2["linkid"] == $r1['value']) // found it, now look for the numbers that we'll put in an array { echo "---here the content---"; // linksuborder is where numbers from row id's are stored like 5,2,8 //now put them in an array $array2 = explode(",", $Row2["linksuborder"]); sort($array2); for ($n2 = 0; $n2 < count($array2); $n2++){ $r2 = each($array2); ////// here searching for the sublinks ////// While ($Row3 = mysql_fetch_array($ResultShow)) { if($Row3["linkid"] == $r2['value']) // search for the right row id within the variable $ResultShow { echo "---here the content---"; break; // found it, so no need to do the rest of the loop } // end if } //end while ////// end searching for sublinks ////// } // end for } // end if else { echo "--- content here ---"; } } // end while } // end for } //end if } // end if Table : linkid linksuborder linktitle 1 2,3,4 2 9,7,8 mainlink1 3 10 mainlink2 4 mainlink3 5 6 7 sublink3 8 sublink2 9 sublink1 10 sublink4 -> linksuborder 2,3,4 are the row id's for the mainlink -> than we put the numbers 9,8,7 (also row id's) mentioned in row linkid 2 also in a new array -> now we can search for the sublinks -> get the details from row linkid 9, than 7, than 8 -> First mainlink is compleet, now go to row linkid 3 to do it all over again for the next mainlink... RESULTS from an sorted array -> sort($linksuborder); ------------------------------------------------------------- mainlink1 : sublink1, sublink2, sublink3 mainlink2 : **no result back but it should * mainlink 3 : **no result back but it should * I'm having a really bad brain fart and I cannot get the logic correct here lol. I need divs wrapped around every set of 5 images so if there is a total of 8 images then there would be 2 sets of divs (first with 5 images, second with 3 images) and if there was 12 images then there would be 3 sets of divs (first two with five images, last one with 2 images) etc etc What am I doing wrong and is there an easier way to do this? http://pastebin.com/QfsFxe4G Thanks! I have this script that asks the user their name and email address and age and stuff and it checks to see what their age is and outputs a message depending on what age bracket they belong to. I am trying to make a for loop that uses the value the user submitted for their age and output the range of numbers from the users age to 1000 by 3s, i know how the basic for loop works, but i don't know how to do one where you are using a variable for i. if that makes sense. Heres the code that i have. test1.html Code: [Select] <!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" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Feedback Form</title> </head> <body> <div><p>Please complete this form to submit your feedback:</p> <form action="test1.php" method="post"> <p>Name: <select name="title"> <option value="Mr.">Mr.</option> <option value="Mrs.">Mrs.</option> <option value="Ms.">Ms.</option> </select> <input type="text" name="name" size="20" /></p> <p>Email Address: <input type="text" name="email" size="20" /></p> <p>Age: <input type="text" name="age" size="20" /></p> <p>Response: This is... <input type="radio" name="response" value="excellent" /> excellent <input type="radio" name="response" value="okay" /> okay <input type="radio" name="response" value="boring" /> boring</p> <p>Comments: <textarea name="comments" rows="3" cols="30"></textarea></p> <input type="submit" name="submit" value="Send My Feedback" /> </form> </div> </body> </html> test1.php Code: [Select] <!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" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Your Feedback</title> </head> <body> <?php include('test1.html'); $name = $_POST['name']; $age = $_POST['age']; $okay = TRUE; if(empty($name)){ echo '<p class="error"> Please enter your name.</p>'; $okay = FALSE; } if (empty($age)){ echo '<p class="error"> Please enter you age.</p>'; $okay = FALSE; } if ($age < 65){ echo '<p>no retirement for you</p>'; } if ($age == 65){ echo '<p> Yay, you can retire</p>'; } if ($age > 65 || $age < 100){ echo '<p>Florida is for me!</p>'; } if ($age > 100){ echo '<p>Good Genes</p>'; } //print users age to 1000 by 3s for($i=$age; $<1000 i+3){ echo '$age'; } ?> </body> </html> I need to pull information from a db table for a slideshow on my page, and need a little help. All of the {$image}'s need to be pulled out and displayed in a div#slider first, then if $caption is set to 1, the caption info is displayed in a div#htmlcaption after the images div#slider. I have an example of the divs below the mysql query, but I'm not sure how to insert it into the while loop. TIA Code: [Select] <?php $sql = mysql_query("SELECT * FROM slideshow"); if(mysql_num_rows($sql) > 0) { while($row = mysql_fetch_assoc($sql)) { $slideID = $row['slideID']; $image = $row['image']; $caption = $row['caption']; $caption_h3 = $row['caption_h3']; $caption_content = $row['caption_content']; $caption_link = $row['caption_link']; $caption_link_text = $row['caption_link_text']; } } ?> Code: [Select] <div id="slider"> <img src="{$image}" alt="" title="#htmlcaption{$slideID}" /> <img src="{$image}" alt="" title="#htmlcaption{$slideID}" /> <img src="{$image}" alt="" title="#htmlcaption{$slideID}" /> </div> <div id="htmlcaption{$slideID}" class="nivo-html-caption"> <h3>$caption_h3</h3> <p>$caption_content</p> if($caption_link != '') { <p><a href="{$caption_link}">{$caption_link_text}</a></p> } </div> Cheers lmfao. I feel like a complete idiot. |
