Similar TutorialsCan 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[$key]);?>"></p> <?php } ?> <input name="Update" type="submit" value="Update"> </form> <?php } ?> </div> Hi all, Using a form with check boxes divided into different categories, I collect data selected by the user. I now want to combine each choice in each category with each choice in the other categories and list the combinations to the user. If the user chooses one or more options in each category, it is relatively easy to nest foreach loops, since the number of categories will always be the same. For example, if the form contains three categories of options, the code will be: Code: [Select] foreach ($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. 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
Hi,
<?php
$string = "Mavic Mini, un quadrirotor reprenant le design pliable de ses aînés, mais pesant cette fois moins de 250 g et disposant de la meilleure autonomie de la famille 30 minutes annoncées.";
$tmp = new clsMarkov();
$tmp->makeList($string);
$tmp->buildTree();
print $tmp->phraseWriter('le', 111); // phraseWriter(mot de base, nombre de mots dans le résultat)
?>
On the last line the script says that the text must start with "le" and the text must be 111 words long. 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! How to generate a unique random number in php??? Any one who can help me? 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. -------------------------------- This might be a bit hard to explain! I have a grid, 32x32 which is actually 1024 mySQL rows in a table, you can see the table he http://interbitlotto.com/grid each cell is a row in the database, top left is ID 1, bottom right is id 1024. get it? right well its a battle ship game, and im stuck on the automatic battle ship placement script. I have displayed the generated boats as misses so we can see them. The problem i am having, is that the random number generater chooses a cell too close to the side so the boat ends up wrapping to the other side. I cant think of a way to detect if its going to wrap, if it is then choose another cell... The code below chooses the orientation of the boat, then chooses a random cell... but as you can see, no code for "across" to stop it choosing one too close to the side. Any ideas? Code: [Select] $orientation = rand(1,2); //get random orientation - 1 = down, 2 = across. if ($orientation == 1){ $multiply = 32; //cells till next row $max = 1024 - (32 * $boatlength); //prevents it from choosing a cell too close to the bottom $startcell = rand(1,$max); }else{ $multiply = 1; //across, so next cell $max = 1024; $startcell = rand(1,$max); } I am looking to generate a random number for every user contribution as a title of the contribution. I could simply check the database each time with a query and generate a number which does not equal to any of the entries of the database. But I imagine this as inefficient and it could become slow if the database is big in my opinion. Also I'd have to contain all the numbers of the database somewhere to manage the "not equals to", in an array or something similar but that can end up as a giant one. Excuse the layman's speech I am new to this. Any suggestions how this can be solved efficiently without straining the resources too much? You can explain it linguistically and do not have to provide me any scripts, I will figure it out. hi!, is it possible to use rand() to generate unique number that will be saved in a database as a primary key? Since i dont want to have numbers like 00001 incrementing on the table. They dont look like real account numbers... i need something like 45642 or 95452 and the like. thanks in advance. 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 I'm attempting to set up a script that will choose a "random" image from a directory and then place it in an article when it's posted. I currently have a php file that randomly assigns a picture on each refresh, however my employer wants the image to be static after posting. So I guess the short of my question is, what would be the best way to go about something like that or is it even doable with PhP. 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']); Hi there - can anyone lend me a little advise as to what I'm doing wrong here.
