PHP - Can One Use "foreach" When The Number Of Arrays Doubles Each Time Through
Greetings to all!
I am very new to this so I may not be on the right track. I am providing some code I have because I think this is the best way to explain what I am trying to do. I have a database and php pages that generate a pedigree when one selects any particular dog from the search page. If anyway has a tip on how to simplify this, I would sure appreciate it!! First, I request an array for the dog selected: Code: [Select] $sql = "SELECT RegName, SireID, DamID FROM pedigrees WHERE ID="; $thisDogQ = $sql . $values["ID"]; $thisDogR = db_query($thisDogQ,$conn); $thisDogRow_value = mysql_fetch_assoc($thisDogR); $thisDogRow_value = array ( 'RegName' => $thisDogRow_value['RegName'], 'SireID' => $thisDogRow_value['SireID'], 'DamID' => $thisDogRow_value['DamID']); </code> //Next I request the same information for his sire <code> if (is_numeric($thisDogRow_value['SireID'])) { $query_SireQ = $sql . $thisDogRow_value['SireID']; $SireR = mysql_query($query_SireQ, $conn) or die(mysql_error()); $SireRow_value = mysql_fetch_assoc ($SireR); $SireRow_value = array ( 'RegName' => $SireRow_value['RegName'], 'SireID' => $SireRow_value['SireID'], 'DamID' => $SireRow_value['DamID']); </code> //and then his dam <code> if (is_numeric($thisDogRow_value['DamID'])) { $query_DamQ = $sql . $thisDogRow_value['DamID']; $DamR = mysql_query($query_DamQ, $conn) or die(mysql_error()); $DamRow_value = mysql_fetch_assoc ($DamR); $DamRow_value = array ( 'RegName' => $DamRow_value['RegName'], 'SireID' => $DamRow_value['SireID'], 'DamID' => $DamRow_value['DamID']); </code> Now, here's the rub: Now I need the sire and the dam for those 2 [described above] so this time through, I will need the same information for FOUR dogs. The next time will be for EIGHT, then SIXTEEN - and so on until there are a total of 256 dogs. <code> //Get PatGrandSire 2 if (is_numeric($SireRow_value['SireID'])) { $PatGrandSireQ = $sql . $SireRow_value['SireID']; $PatGrandSireR = mysql_query ($PatGrandSireQ, $conn) or die(mysql_error()); $PatGrandSireRow_value = mysql_fetch_assoc ($PatGrandSireR); $PatGrandSireRow_value = array ( 'RegName' => $PatGrandSireRow_value['RegName'], 'SireID' => $PatGrandSireRow_value['SireID'], 'DamID' => $PatGrandSireRow_value['DamID']); //GetPatGrandDam 17 if (is_numeric($SireRow_value['DamID'])) { $PatGrandDamQ = $sql . $SireRow_value['DamID']; $PatGrandDamR = mysql_query ($PatGrandDamQ, $conn) or die(mysql_error()); $PatGrandDamRow_value = mysql_fetch_assoc ($PatGrandDamR); $PatGrandDamRow_value = array ( 'RegName' => $PatGrandDamRow_value['RegName'], 'SireID' => $PatGrandDamRow_value['SireID'], 'DamID' => $PatGrandDamRow_value['DamID']); //Get Pat1GGrandSire-3 if (is_numeric($PatGrandSireRow_value['SireID'])) { $Pat1GGrandSireQ = $sql . $PatGrandSireRow_value['SireID']; $Pat1GGrandSireR = mysql_query ($Pat1GGrandSireQ, $conn) or die(mysql_error()); $Pat1GGrandSireRow_value = mysql_fetch_assoc ($Pat1GGrandSireR); $Pat1GGrandSireRow_value = array ( 'RegName' => $Pat1GGrandSireRow_value['RegName'], 'SireID' => $Pat1GGrandSireRow_value['SireID'], 'DamID' => $Pat1GGrandSireRow_value['DamID']); if (is_numeric($PatGrandSireRow_value['DamID'])) { $Pat1GGrandDamQ = $sql . $PatGrandSireRow_value['DamID']; $Pat1GGrandDamR = mysql_query ($Pat1GGrandDamQ, $conn) or die(mysql_error()); $Pat1GGrandDamRow_value = mysql_fetch_assoc ($Pat1GGrandDamR); $Pat1GGrandDamRow_value = array ( 'RegName' => $Pat1GGrandDamRow_value['RegName'], 'SireID' => $Pat1GGrandDamRow_value['SireID'], 'DamID' => $Pat1GGrandDamRow_value['DamID'], 'Title' => $Pat1GGrandDamRow_value['Title'], 'Title2' => $Pat1GGrandDamRow_value['Title2'], 'Title3' => $Pat1GGrandDamRow_value['Title3'], 'Title4' =>$Pat1GGrandDamRow_value['Title4'], 'Title5' => $Pat1GGrandDamRow_value['Title5'], 'Title6' =>$Pat1GGrandDamRow_value['Title6'], 'Title7' => $Pat1GGrandDamRow_value['Title7'], 'Title8' =>$Pat1GGrandDamRow_value['Title8'], 'Title9' => $Pat1GGrandDamRow_value['Title9'], 'Addl_Titles' => $Pat1GGrandDamRow_value['Addl_Titles']); //Get Pat2GGrandSire-18 if (is_numeric($PatGrandDamRow_value['SireID'])) { $Pat2GGrandSireQ = $sql . $PatGrandDamRow_value['SireID']; $Pat2GGrandSireR = mysql_query ($Pat2GGrandSireQ, $conn) or die(mysql_error()); $Pat2GGrandSireRow_value = mysql_fetch_assoc ($Pat2GGrandSireR); $Pat2GGrandSireRow_value = array ( 'RegName' => $Pat2GGrandSireRow_value['RegName'], 'SireID' => $Pat2GGrandSireRow_value['SireID'], 'DamID' => $Pat2GGrandSireRow_value['DamID'], 'Title' => $Pat2GGrandSireRow_value['Title'], 'Title2' => $Pat2GGrandSireRow_value['Title2'], 'Title3' => $Pat2GGrandSireRow_value['Title3'], 'Title4' => $Pat2GGrandSireRow_value['Title4'], 'Title5' => $Pat2GGrandSireRow_value['Title5'], 'Title6' => $Pat2GGrandSireRow_value['Title6'], 'Title7' => $Pat2GGrandSireRow_value['Title7'], 'Title8' => $Pat2GGrandSireRow_value['Title8'], 'Title9' => $Pat2GGrandSireRow_value['Title9'], 'Addl_Titles' => $Pat2GGrandSireRow_value['Addl_Titles']); //Get Pat2GGrandDaminfo-25 if (is_numeric($PatGrandDamRow_value['DamID'])) { $Pat2GGrandDamQ = $sql . $PatGrandDamRow_value['DamID']; $Pat2GGrandDamR = mysql_query ($Pat2GGrandDamQ, $conn) or die(mysql_error()); $Pat2GGrandDamRow_value = mysql_fetch_assoc ($Pat2GGrandDamR); $Pat2GGrandDamRow_value = array ( 'RegName' => $Pat2GGrandDamRow_value['RegName'], 'SireID' => $Pat2GGrandDamRow_value['SireID'], 'DamID' => $Pat2GGrandDamRow_value['DamID']); Similar TutorialsHi all, Using a form with check boxes divided into different categories, I collect data selected by the user. I now want to combine each choice in each category with each choice in the other categories and list the combinations to the user. If the user chooses one or more options in each category, it is relatively easy to nest foreach loops, since the number of categories will always be the same. For example, if the form contains three categories of options, the code will be: Code: [Select] foreach ($form['cat_1'] as $k1 => $val1) { foreach ($form['cat_2'] as $k2 => $val2) { foreach ($form['cat_3'] as $k3 => $val3) { echo $val1.' _ '.$val2.' _ '.$val3.'<br/>'; } } } Things get complicated if the user does not select options within a given category. More generally, I want to be able to generate the list regardless of the number of categories in which the user selects options. Thank you in advance for your advice. Can someone please help me with an array problem i can not figure out. I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array. 1, "mysql_field_name", "Title of form field" 2, "", "" and so on then the form will be shown based on the array. I have the following draft code which I am working with. any suggestions on how i may do this array ? Code: [Select] <?php $options = array( '1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'), '2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'), '3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'), '4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'), ); // $options = array(1 => "option1", "option2", "option3", "option4"); // the line above works but i want to include the name of the mysql field as well. $userid = 1; ?> <div style="align: center; margin: 12px; font-family:Tahoma;"> <br><br><?php if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql. $res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'"); foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); } $ok_to_update = "no"; } elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data. // error checking // foreach($options as $key => $value) { // $_POST[$i] = ""; // } $ok_to_update = "yes"; } if ($_POST['Update'] == "Update" && $ok_to_update == "yes") { // $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database. ?><p><br><br><br>Thank you for updating</p><?php } else { ?><form name="form1" method="post" action=""> <?php foreach($options as $key => $value) { ?><p><?php echo($value); ?>: <input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p> <?php } ?> <input name="Update" type="submit" value="Update"> </form> <?php } ?> </div> Hi, bit stuck on how to find and replace "<" and ">" with "<" and ">". I basically have a database record that outputs to screen and I need the code in the <code> tags to be rendered to the screen. I therefore need it to go through the whole array variable from the db and change the symbols just inside the code tags. Please be aware that the code tags might happen more than once here's an example below Code: [Select] <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1> </code> the desired output would be: <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> <p>blah blah blah</p> <p>blah blah blah</p> <p>blah blah blah</p> <code> <h1>hello</h1 </code> help on this would be great Cheers Rob Hey Guys!

Really looking forward for some help on this one, Thanks a lot in advance! Cheers! hello how do i pass a foreach loop through "Passing by Reference" say i have a foreach loop in a function like this: Code: [Select] function findText(&$output){ $word = Text::find_all(); foreach ($word as $words){ $output = $words->text; } } then one the page i put Code: [Select] findText($output); echo $output; that will just give me the last word in the database. so how do i get it to echo out the array on the page ? thanks Hi guys I am a newbie with PHP and I have been trying to solve this problem for 3 days.. Ive set up a booking form on my website to be sent directly to my email once the client clicked on the send button.. The problem I am having while checking these pages on wamp is that the booking form is ok but when I click on the send button the following message error appears "Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\wamp\www\fluffy_paws\booking_form2.php on line 27" When I check online I have this message "500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed." Are my codes wrong??? My webhosting is Blacknight.com , Im on Windows Vista, my internet is a dongle with O2 ireland Thanks for your help! Hi Guys Ever had the feeling your being a spoon and can't see the wood for the trees? Well, that's how I feel today. All I am trying to to is implement a variable in a "foreach" loop that increments by one through each iteration of the loop. I know how to do it in a "for" loop but can't for the life of me get it to work here. Here is the code: foreach ($cart as $prodcode => $qty) { $item = get_product_details($prodcode); echo '<input type="hidden" name="item_name_'.[b]$needavariablehere[/b].'" value="'.$item['description'].$_SESSION['finish'][$prodcode].$_SESSION['handles'][$prodcode].'" />' . "\n"; } Where I have highlighted $needavariablehere is where I want a number to appear i.e. if there is one item available and the foreach loop iterates once I want the number 1 here. If there are two items and the foreach loop iterates twice I want the output to have number 1 in the first line and number 2 the second time around and so on. How many times the foreach loop iterates is based on the $cart array which contains items in a shopping cart. Thanks for any help you can give guys. question of perfomance .. Code: [Select] //take the names from table1 apply($sql1); foreach($names as $name){ //grab other info about the current user from table2 apply($sql2); } is this fine ? Hi everyone, I have the task of building a PHP page where users can enter or remove as many records as they like into different categories. This then makes the number of records entered unknown, and therefore it becomes more complicated. To make this clearer, I have attached an image of what I am trying to do. Two questions: - Before submitting the form, how can each record entry be matched with the correct category? (maybe hidden form fields somehow?) - What is the best way of inserting each record (and it's associated category) into a MySQL database table from a single form submit? I want to try and keep this as simple as possible as the data will later be updated, removed etc. I'm experiencing a brain fart and just cannot picture the best way of going about this Any help and advice is much appreciated! Thanks in advance. Code: [Select] Basic table schema example... CATEGORY TABLE ---------------------------- | catid | category | ---------------------------- | 1 | Category A | | 2 | Category B | etc. etc. ---------------------------- DATA ENTRY TABLE ---------------------------- dataid | catid | data | -------------------------------- | 1 | 2 | data xyz | | 2 | 1 | data zyx | etc. etc etc. -------------------------------- Hi guys I'm struggling a bit, I need to replace a word that occurs multiple times in text with an array("up","down","forward","backwards") of words. $find = "left"; $replace = array("up","down","forward","backwards"); $text = "left left left left"; echo str_replace($find,$replace,$text); The Output is: array array array array Did try this with a foreach statement as well, but no luck. Is there a better way of doing this? Thanks Greetings, My first post here. I'm learning PHP as rapidly as I can, but I still have some basic questions. OK, I'm trying to run the Gallerific gallery script on my site. The way Gallerific works, it looks at an unordered list to populate the gallery. In each list item, it grabs a main image and a thumbnail image. I have folders that are created dynamically as a user uploads photos. There is a main folder and a "thumbs" sub-folder. That's all taken care of before the script comes into play I need to loop through both the main images and the thumbnails at the same time, and call each one in the list items. I know this code must be wrong, but I'll post it as a starting place. Can someone help me figure out how to do this correctly? Maybe I should not even be using foreach? Code: [Select] <div id="thumbs" class="navigation"> <ul class="thumbs noscript"> <?php foreach($cck->get( 'property_listing_images' )->value as $large){ foreach($cck->getValue( 'property_listing_images' )->value as $thumb1){ ?> <li> <a class="thumb" href="images/<?php echo $large->value; ?>" title="Title X"> <img src="images/<?php echo $thumb1->value; ?>" alt="Title X" /> </a> </li> </ul> <?php } ?> <?php } ?> </div> Thank you ahead of time for your help! Matthew Hi everyone, I am just starting out with php so I am sure this is a really silly question. I have been working through php & mySQL for dummies (latest edition) and each time I read a new chapter I try to implement the tutorial. I have been trying something really simple from the book and have now even tried copying it word for word but it still will not work. I am basically trying to output a list of Cities and States with the following code: <?php $capitals = array ("CA" => "Sacramento", "TX" => "Austin", "OR" => "Salem" ); foreach ($capitals as $state => $city); ksort ($capitals); { echo "$city, $state<br />"; } ?> Instead of getting: Sacramento, CA Salem, OR Austin, TX I just get: Salem, OR I am running XAMPP on Mac OS X 10.6.5. Any ideas or help would be awesome! cant work out this mysql syntax error "operation":"medupdate","medid":"","name":"ibo","medyear":"5","medmonth":"21","medday":"1","recuser":1,"SuccFail":"fail","SuccFailMessage":"error occured You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '''WHERE med_id=' at line 2","ResultData":""} Code: [Select] $sql="update metodology set med_description='".$req['name']."', med_year='".$req['medyear']."', med_month='".$req['medmonth']."', med_day='".$req['medday']."', med_recorddate= now(), med_recorduserid= 1'"; $sql.= " WHERE med_id=".$req['medid']; Hello, Do you guys have any idea how to start an Automatic Order Number System in PHP? I have an service Website, where you can purchase something, and i want after the redirect to "Success.php" to generate an order number, to be shown to the buyer and saved in Date Base for me. Any solutions helps. I´m beginner so don´t mind
Hello I am trying to only display results within the time period last sunday too next sunday. my code: Code: [Select] <?php $today = date('Y-m-d H:i:s'); $time = strtotime($today); $last_sunday = strtotime('last sunday', $time); $next_sunday = strtotime('next sunday', $time); $format = 'Y-m-d H:i:s'; $last_sunday = date($format, $last_sunday); $next_sunday = date($format, $next_sunday); ?> <?php $sql_totalsurfs = ("SELECT vtp_members.id, vtp_members.name, vtp_members.teamleader, vtp_tracking.Timber, vtp_tracking.Stone, vtp_tracking.Marble, teams.team_name, count(vtp_tracking.id) surfs FROM vtp_members, vtp_tracking, teams WHERE vtp_members.team_id=".$_GET['t']." AND vtp_tracking.credit_members_id=vtp_members.id AND vtp_tracking.action_date>'$last_sunday' AND vtp_tracking.action_date<'$next_sunday' GROUP BY vtp_members.id ORDER BY surfs DESC LIMIT 0, 10"); $rstotalsurfs = mysql_query($sql_totalsurfs); $numrows = mysql_num_rows($rstotalsurfs); ....... Is there and error somwhere in the code? I apologizing for bothering the expert here again, but I've run into another issue. I am using the following code because I can't change the default timezone on my shared hosting plan:
$time = date("h:i A", strtotime("+19 hours"));
there are few issues with this. if I just use: date("h:i: A") the time prints as 7 hours earlier than my timezone, and currently it shows 1:09 AM and it appears in the database as "01:09:00". if I use the code above, the time prints out as "08:09 PM", but it is inserted into the database as "08:09:00". Shouldn't it read "20:09:00" instead? and why isn't the time being inserted into the database with the "PM" suffix on it like it appears in the printout? the "time" field in my database is set to type TIME. thanks. Edited October 14, 2019 by ajetrumpetI am getting the following error when using composer: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? Just started. I am pretty sure composer.json wasn't changed. journalctl doesn't show anything. Maybe Doctrine related, however, nothing seems to help.
Any ideas?

Question:
Background:
Example: The Pacific ("Los Angeles") time right now is 7:58pm, but my code says it's 6:58pm. So now I have to go in and correct the "PT8H" portion. I'm wondering if there is some code I can use whereby I can simply "set it and forget it." Thank you! Edited May 2, 2020 by StevenOliver |
