PHP - How Can I Make Two Array Slicing An Array?
Given array
Code: [Select] Array ( [Post] => Array ( [title] => new with has many through for tags [body] => hello tags [category_id] => 11 [tags] => one two three [mark] => 1 ) ) I need to make an array something like this: Code: [Select] Array ( [Post] => Array ( [title] => new with has many through for tags [body] => hello tags [category_id] => 11 [mark] => 1 ) [Tag] => Array ( [0] => Array( [name] => one ) [1] => Array( [name] => two ) [2] => Array( [name] => three ) ) ) How can i make it? Similar TutorialsHey, I've been developing a browsergame. In this you are able to produce something ("weed"). Now I've got some kind of trouble with the function that is responsible for updating the "weed" on the user accounts. Im going to explain, how my script is working First step: Loading the datas from "worlds". In this case id, weed_factor, weed_basis. What this is required for you will see in the next steps <?php include 'includes/settings/mysql.php'; mysql_connect($dbhost, $dbuser, $dbpass); mysql_select_db($dbbase); $time = time(); $update_weed_world_data_sql = "SELECT id, weed_factor, weed_basis FROM worlds"; $update_weed_world_data_res = mysql_query($update_weed_world_data_sql) OR DIE (mysql_error()); while($update_weed_world_data_while = mysql_fetch_assoc($update_weed_world_data_res)){ $update_weed_world_id = $update_weed_world_data_while['id']; $update_weed_world_basis[$update_weed_world_id] = $update_weed_world_data_while['weed_basis']; $update_weed_world_factor[$update_weed_world_id] = $update_weed_world_data_while['weed_factor']; global $update_weed_world_basis; } Second step: This is the function which is editing each account by the data given as parameters. function do_update_weed($profile_id,$world,$update,$level,$time){ $update_weed_period = $time - $update; $update_weed_add = ($update_weed_period / 3600 * $update_weed_world_basis[$world] * pow($update_weed_world_factor[$world],$level)) +1; echo $update_weed_world_basis[$world]; echo "<br>"; mysql_query("UPDATE profiles SET weed = weed +$update_weed_add, weed_update = $time WHERE id = $profile_id LIMIT 1"); } Note: echo $update_weed_world_basis[$world]; doesnt result an output. In step three, the accounts are loaded: function todo_update_weed($time){ $todo_update_weed_sql = "SELECT * FROM profiles WHERE weed_update < $time"; $todo_update_weed_res = mysql_query($todo_update_weed_sql) or die (mysql_error()); while($todo_update_weed_while = mysql_fetch_assoc($todo_update_weed_res)){ do_update_weed( $todo_update_weed_while['id'], $todo_update_weed_while['world_id'], $todo_update_weed_while['weed_update'], $todo_update_weed_while['level_farm'], $time ); } } And the last step is calling function "todo_update_weed" with the time. todo_update_weed($time); I script calculate the time between the last update and the current time. This make a difference in time. With this value I calculate something else. And then the update time has to be saved. The script has just working fine, when I set the variable "$update_weed_add" with a fix value. But by now the script doesn't work, because I don't know how to make the array available inside functions. I considered whether I put the database-function for the world_data inside the function that updates the profiles. But if I do this, the database will be called thousands of times... Hope anybody has a nice idea to fix the problem Ok, so this seems kinda vague, cus normally thats what you do, however I am talking about a differnt kinds of output from a query... Here is what i am a talking about: My Query Code: $query = "SELECT * FROM settings WHERE storeid='store350' "; $which = $handle_db2; $result = mysql_query($query,$which); $num = mysql_num_rows ($result); $id = mysql_result($result,$i,"id"); $storeid = mysql_result($result,$i,"storeid"); $tinypass = mysql_result($result,$i,"tinypass"); $taxsetting = mysql_result($result,$i,"taxsetting"); $gst = mysql_result($result,$i,"gst"); $pst = mysql_result($result,$i,"pst"); $hst = mysql_result($result,$i,"hst"); $canpar = mysql_result($result,$i,"canpar"); $cp_fuelcharge = mysql_result($result,$i,"cp_fuelcharge"); $cp_markup = mysql_result($result,$i,"cp_markup"); $fedex = mysql_result($result,$i,"fedex"); $fe_fuelcharge = mysql_result($result,$i,"fe_fuelcharge"); $fe_markup = mysql_result($result,$i,"fe_markup"); $dhl = mysql_result($result,$i,"dhl"); $dh_fuelcharge = mysql_result($result,$i,"dh_fuelcharge"); $dh_markup = mysql_result($result,$i,"dh_markup"); $tnt = mysql_result($result,$i,"tnt"); $tn_fuelcharge = mysql_result($result,$i,"tn_fuelcharge"); $tn_markup = mysql_result($result,$i,"tn_markup"); As you can see, my variables are the same as my table column names... now if this "project" goes thorugh I could have hundreds of columns, I would hate to have to define each one making my file even larger. Is there a way to make it dynamically create the variables via an array or something Theoriticaly something like this: $query = "SELECT * FROM settings WHERE storeid='store350' "; $which = $handle_db2; $result = mysql_query($query,$which); $num = mysql_num_rows ($result); (While loop here) $Table_name_var = mysql_result($result,$i,"table_name"); (end while loop) Possible?
This is the cart array: I want the key to be "id" and the value to be "quantity" like it is for the cart array. How do I define my cart_items array using variables? If I have a db with these fields: displayname, title and I run a successful query on the db, will this code: if (mysql_num_rows($results) == 0) { return "!fail"; } else { while ($row = mysql_fetch_assoc($results)) { extract($row); } return $row; } create an associative array of $var = array(array('displayname' => value, 'title' => value), array('displayname' => value, 'title' => value)...) If not, is there a way to do so, especially when I will not know the names or number of fields in a db table? Hi, As the title suggests I am unsure on how to first run a query which stores values into an array. I then need to run a function multiple times but use the array within the function. How is this possible? I have had no luck figuring it out yet. 1. RUN QUERY 2. BUILD ARRAY USING QUERY RESULTS 3. RUN FUNCTION MULTIPLE TIMES 4. WITHIN FUNCTION I NEED TO USE ARRAY Many thanks Simon Hello, everyone: I'm using PHP and Mysql. I've got a table of that has 30 fields that I need to add together. I've got to do this for each record, and there are about 10,000 records. Which would be more efficient? SELECT SUM( field1 + field2...) or to make an array for the fields and then use array_sum() Thanks. I have the following code: Code: [Select] private function buildJSResponse(){ $data = ""; $i = 0; $arr = array(); while($this->db->row()){ $arr[] = (int)$this->db->field("average"); } $this->max = max($arr); $this->min = min($arr); $this->mid = round(($this->max + $this->min) / 2); foreach($arr as $val){ $nTime = ($val / $this->max) * 100; $data .= "data[$i] = ".$nTime.";"; $i++; } return $data; } It takes an array, finds the max/min and number halfway between the min/max. The next part I am not sure what to do. I am making a line graph using the canvas, so I am building a javascript array, which will contain the point on the chart. The problem I am having, is location. Lets say $max = 110, and $min = 95. the y position on the graph should be 0 for $max, and 100 for $min, then all the other points need to fall into their place as well. $nTime is supposed to do that, but it doesn't any suggestions? The attachment is the result I am getting from my above code. As you can see the lowest number is 49, so the value with 49 should touch the bottom, which it doesn't. ok .. so I have this object and I want to make a tab delimited text file from it. here's what I have so far. function create_tab_file_from_object($the_object) { $string = ''; foreach($the_object as $val) { $string .= $val.'\t'; } //drop last tab $string = substr($string,0,-2); filename = 'test_file_pickup.txt'; $fp = fopen('/filepath/'.$filename,'w'); fwrite($fp,$string); fclose($fp); } when i run this i get a text file that looks something like this field1\tfield2\tfield3\t ... and so on. How do I get php to make an actual tab delimited file I can open in notepad or excel or whatever.. Thanks in advance, C hi friends, I am using one API in which i need to make request for flight search, i am using soapclient to connect with the server to fetch available flights, below is the xml in which request format will be.

Please correct my request in case i made bad request for the server. stdClass Object ( [Ws_fnAirAvailResult] => stdClass Object ( [objclsException] => stdClass Object ( [errorcode] => GEN0E0006 [errortype] => E [errordesc] => Please provide Security object. ) [strMessage] => ) ) I am using a WordPress theme that uses some of its own functions besides WP functions. Let me make clear from the start that when I say "Multiple Checkboxes" in the paragraphs below I am NOT talking about checkboxes that each hold a single value. I am talking about one Checkbox field that allows multiple values to be selected and puts those values into an array with one Name value and stores the output in a string in a single mysql table field. Right up front, what I need during the Edit Ad functions is the inbuilt function that will Delete the previous Array of values in any multiple checkbox when the ad is updated. Right now updating the ad works for every situation except NO values selected or for Unchecking all previously selected values in a Multiple Checkbox. If I have, for example, 4 checkboxes selected and unselect all of them before submitting the edited ad it will return the last saved array of values but not an Empty array with no checkboxes selected. This theme has a Form Builder with a Custom fields builder used by the admin to create forms for a classified ads website. According to which category of ad the Ad creation procedure will show different forms, with different fields. I had to manually create the capability to generate multiple checkboxes...so that the different multiple checkboxes when selected and updated to the mysql table might hold a variety of values in a comma-delimited array. That works fine. When the Ad is edited on its own page, (outside of the Wordpress admin dashboard) the problem is that if a user would uncheck all checkboxes in a particular multiple checkbox then the unselected state does not overwrite the previous array of values. What returns after editing is the previous selected values. I have tried jquery functions but none of them are working the way I had hoped. so one type of checkbox might have a hypothetical value like this "name="cp_checkbox_help[]" and if three options are selected then on submit the value could be--- name="cp_checkbox_help[Sunday,Monday,Tuesday]" I use implode and explode to store the array as comma separated and retrieve the array for editing or display. I guess I need to create a Null or empty value as a default that only changes when selections are made. But, since I use implode and explode to make the array "pretty" I don't know if simply specifying nothing will erase a whole array on update. Here is some of the code used to see how I get what I get-- This displays the checkboxes that I create and name and fill with different values-- case 'checkbox': ?> <?php $options = explode(',', $result->field_values); echo '<div id="checkboxes"><table width="100%" border="0" cellspacing="0" cellpadding="5"> <tr> <th colspan="2" scope="col">' . $result->field_label. '</th> </tr>'; $myvals= explode(',', $post_meta_val); foreach ($options as $option) { { ?> <tr> <td width="4%"><input style="display:inline-block; float:left;" type="<?php echo $result->field_type; ?>" name="<?php echo $result->field_name; ?>[]" class="checkbox<?php if($result->field_req) echo ' required'?>" id="<?php echo $field_label; ?>" value="<?php echo $option; ?>" <?php foreach ($myvals as $myval) { if (in_array($myval, array($option), true)) {echo 'checked="yes"';}}?>/></td> <td width="96%"style="vertical-align:top; text-indent: 7px; text-align: left;" ><?php echo $option . '</td> </tr> ' ?> <?php } } echo ' </tr> </table></div><div class="clr"></div>'; break; Following is the main part of the code that updates the Ad form-- // update the ad and return the ad id $post_id = wp_update_post($update_ad); if($post_id) { // now update all the custom fields foreach($_POST as $meta_key => $meta_value) { if (cp_str_starts_with($meta_key, 'cp_')) if (cp_str_starts_with($meta_key, 'cp_checkbox_charley')) $meta_value= implode(',', $_POST['cp_checkbox_charley']); if (cp_str_starts_with($meta_key, 'cp_checkbox_help')) $meta_value = implode(',', $_POST['cp_checkbox_help']); if (cp_str_starts_with($meta_key, 'cp_checkbox_hello')) $meta_value= implode(',', $_POST['cp_checkbox_hello']); //echo $meta_key . ' <--metakey <br/>' . $meta_value . ' <--metavalue<br/><br/>'; // for debugging update_post_meta($post_id, $meta_key, $meta_value); } $errmsg = '<div class="box-yellow"><b>' . __('Your ad has been successfully updated.','cp') . '</b> <a href="' . CP_DASHBOARD_URL . '">' . __('Return to my dashboard','cp') . '</a></div>'; } else { // the ad wasn't updated so throw an error $errmsg = '<div class="box-red"><b>' . __('There was an error trying to update your ad.','cp') . '</b></div>'; } return $errmsg; } Back on the Edit Ad page this is the Submit <p class="submit center"> <input type="button" class="btn_orange" onclick="window.location.href='<?php echo CP_DASHBOARD_URL ?>'" value="<?php _e('Cancel', 'cp')?>" /> <input type="submit" class="btn_orange" value="<?php _e('Update Ad »','cp') ?>" name="submit" /> I have a feeling what I need is just a couple of lines to detect no posted values and then... but if one checkbox array has 6 values in it and another checkbox array has only 3 values, for example, do I need to count each specific checkbox for number of values and then overwrite or will one function completely delete the previous array and its commas? I would really appreciate some expert assistance here! $looponce = 1; foreach ($this->info as $k => $v) { if ( (($k == 'subject') && ($v['required'])) && (!$this->settings['customSubject'])) { for ($i = 0; $i <= 0; $i++) { $output[] = $this->display_errors('error_system_subject'); } } if ( (($k == 'name') && (!$v['required'])) || ((!array_key_exists("name", $this->info)) && ($looponce == 1)) ) { $output[] = $this->display_errors('error_system_name'); $looponce++; } } That is my loop that i check things in. What i'm more interested in is the name if statement. If currently checks for a name key in an array(below) and makes sure that it is set to required. If it's not set to required, print out a system error and die()'s. I'm looking for ways to remove the need for program errors and just change them to what is needed to run. What i know how to do is, get into the inner array, what i don't know is how to edit the data and put it back exactly as it was given to me. The inner array data can be put back in any order, but the outer array must be in exact order as it was given. above code $this->info = $formdata; $formdata = array( 'name' => array('name'=>"Full Name", 'required'=>false, 'type'=>'text'), # This needs to be required=>true, but i can't trust the user, which is why i have the error. 'telephone' => array('name'=>"Telephone", 'required'=>false, 'type'=>'phone'), ); Any help is greatly appreciated, also am i doing the foreach loop in the code above in an efficient manner or is there another way?

How can i save array from inputs, witch is $igraci and it have 5 values, to mysql base, i tryed but in mysql it shows Array. This is form: <form action="dodaj_klan.php" method="post" > <p> <label>Naziv klana:</label> <input name="naziv" type="text" size="20%" /> <label>Web Sajt:</label> <input name="website" type="text" size="20%" /> <label>E-Mail:</label> <input name="email" type="text" size="20%" /> <br /><br /> <label>Igraci klana(5):</label> <input name="lider" type="radio" value="1" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="2" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="3" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="4" /> <input name="igraci[]" type="text" size="20%" /><br /> <input name="lider" type="radio" value="5" /> <input name="igraci[]" type="text" size="20%" /> <label><i>(obelezi lidera klana)</i></label> <br /><br /> <input class="button" type="submit" name="submit" value="Dodaj" /> </p> </form> Now i wonna save this igraci[] array in mysql, i tried like this but it doesn't work: $igraci = $_POST['igraci']; $query = "INSERT INTO klanovi (naziv, website, email, igraci) VALUES ('{$naziv}', '{$website}', '{$email}', '{$igraci}')"; $result = mysql_query($query, $connection); How can i do this? Thanks.. I am having some problems getting a query correct. Basically I have two tables, one with listings and another with categories. In the listings table I have a column called shortdescription. I am trying to pull the shortdescription from the listings table with the query $shortdesc = array_shift(mysql_fetch_row(mysql_query("select shortdescription from links where category = '".$scat->id."' "))); The shortdecription display properly on the pages display the listings, however I am getting the following error on any pages that only display the parent categories Warning: array_shift() [function.array-shift]: The argument should be an array in /home/...path/file.php on line 1462 The listings id numbers begin at 75+ because the initial parent category id ends at 74. The query seems to be searching for listing ids below 75 and spitting out an error because it is not finding them. Any ideas on how to eliminate this error and/or stop the query from looking for non-existant data? Using curl_multi, I have loaded up 3 url's and then printed the array. 1) How can I also set a timestamp on output to let me know when each url was run? 2) How can I explode the array to only display the data and timestamp, excluding the text "Array ( =>", "[1] =>", "[2] =>" and " )"?

$result = $mysqli->query($sql, MYSQLI_STORE_RESULT);
if($result)
{
while ($row = $result->fetch_array(MYSQLI_ASSOC))
{
var_dump($row);
}
}
On inspection of the retrieved array with var_dump(), i have these result below:
array (size=2) 'John' => string 'English' (length=2) 'Score' => string '20' (length=3) array (size=2) 'Mary' => string 'Math' (length=3) 'Score' => string '35' (length=3) array (size=2) 'Samuel' => string 'Physics' (length=3) 'Score' => string '5' (length=3)How do I get at and print out the highest score from this set of array values within this context. I tried this echo max($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. Hi there, Basic question, but I can't seem to find a page in the PHP docs that answers (though I'm sure such a one exists, I just can't seem to think up the right search terms - anyway) My question is: is there a short-hand way to use a value from an associative array as the key in another associative array? So for example, given this array: $the_array = array(0 => array('name': 'the_name', 'value' : 'the_value'), 1 => etc....); then this kind of foreach loop doesn't work Code: [Select] $new_data = array(); foreach($the_array as $element){ $new_data[$element['name']] = $element['value']; } Obviously I can just save out the values, like $name = $element['name'] --- but I was just wondering if there was a more efficient way to do it? Cheers, PS. I tried encapsulating with {} - i.e. $new_data[{$element['name']}] --- but that also fails. Hello all, I have yet again trouble finding a logical solution to my problem. I'm fetching an array which can hold 1 or more values. The problem is, I want these values to ouput in my json_encode function, but this also needs to happen dynamically depending on the amount of values. I can't explain it further, so here's the code so far: Code: (php) [Select] $files = mysql_fetch_array($get_files); $a = count($files); $i = 1; while ($files) { $variablename = 'fileName' . $i; $$variablename = $files['fileName']; $i++; } $output = array( OTHER VALUES , 'fileName1' => $fileName1, 'fileName2' => $fileName2, 'fileName3' => $fileName3, ............); // How do I add the fileNames dynamically depending on how many there are? This got me thinking, I also need to dynamically GET the values with jQuery. How would I do that, when the above eventually works? Thank you. So I'm trying to create an Array from a comma separated string containing array{s}. How can I take a string full of comma separated hex values such as : <?php $myStr = ( "00ffff", "00cccc", "009999", "007777", "004444", "001111", "01ffff", "01cccc", "019999" ); ?> & turn it into 3 separated arrays like : <?php $myNewArrs = [ Array1 ( 3 ), Array2 ( 3 ), Array3 ( 3 ), ]; ?> which REALLY looks like :
<?php
$myNewArrs = [
Array ( "00ffff", "00cccc", "009999" ),
Array ( "007777", "004444", "001111" ),
Array ( "01ffff", "01cccc", "019999" ),
];
?>
? Thank you & have a great afternoon!
