PHP - Help With Array: Need To Set Array Value Depending On Value With Higher Priority
Currently, I am trying to make my URL shortener script able to track UTM variables from Google Analytics. I also want to provide my own (campaign/keyword/source/etc...) variables.
I am trying to sift through $_GET, pick out "approved" key/value pairs and set each key with the condition that UTM variables take higher precedence (I only want to store one value in the database). My code is currently: Code: [Select] //Parse $_GET and only get the key/pairs that we need and store them in global $url_params for use through out the script function set_url_params($allowed=NULL) { // $allowed is arg to add new values in future dev global $url_params; $allowed = array( 'l', // Redirect key (e.g http://example.com?l=a1dFd7) 'utm_campaign', 'campaign', 'utm_source' , 'source', 'utm_medium', 'medium', 'utm_term', 'term', 'keyword', 'kw', ); $approved = array_intersect_key($_GET, array_flip($allowed)); foreach($approved as $key => $value) { strip_tags(urldecode(trim($value))); $url_params[$key] = $value; } //Assign variables to global $url_params variable so other functions can use them. //NOTE: Google Analytics UTM parameters take precedence over script values. $url_params['l'] = isset($approved['l']) ? $approved['l'] : NULL ; $url_params['campaign'] = isset($approved['utm_campaign']) ? $approved['utm_campaign'] : $approved['campaign']; $url_params['source'] = isset($approved['utm_source']) ? $approved['utm_source'] : $approved['source']; $url_params['medium'] = isset($approved['utm_medium']) ? $approved['utm_medium'] : $approved['medium']; $url_params['term'] = isset($approved['utm_term']) ? $approved['utm_term'] : $approved['term']; $url_params['keyword'] = isset($approved['keyword']) ? $approved['keyword'] : $approved['kw']; // Just in case $url_params doesn't have a 'keyword' set, we will use 'term' instead. $url_params['keyword'] = isset($url_params['keyword']) ? $url_params['keyword'] : $url_params['term']; } I basically want to find a cleaner way of doing this without all the isset()'s. I also get NOTICE errors (running in E_ALL) for undefined variables that I would like to unset so I don't get those errors. Any help would be appreciated. Thanks. Similar TutorialsHello everyone, i'm kinda stuck here although i had this working before, i don't know what's wrong here. Basically i've got a form with a drop-down menu, that menu has 3 values, x,y and z. Now that form is working with post, sending me to the next page where i have a set of arrays and a echo which should print some text based on the option chosen from the drop down menu. my code in the form is this: Code: [Select] <select name="value1" id="value1"> <option value="x">x</option> <option value="y">y</option> <option value="z">z</option> </select> the array on the next page: Code: [Select] $arrayvalue = array("x"=>"test1", "y"=>"test2", "z"=>"test3"); and the echo: Code: [Select] <?php echo $arrayvalue["value1"];?> That leaves me with an empty page. What am i doing wrong here ? am i missing something ? any help is greatly appreciated. Sabrina NOTE - Please read the information first as it contains important information to understand the problem.

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 " )"?

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. 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. 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!
Edited May 27 by AquariaXI I need a help in the following : I have an admin page from where the admin attaches an gif image.This attached image should be shown to the user as a scrolling image. The code for the scrolling image is done through javascript. So my actual problem is getting the name of the attached gif image to the javascript array which is used for scrolling horizontally. I have mysql select query shown below retrieving data from a database:
$sql = "
SELECT
student, sum( test_score ) as score
FROM
test
INNER JOIN
level
ON
test.level_id = level.level_id
GROUP BY
student"
$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($row['count']) but i understandably got this feedback: Warning: max(): When only one parameter is given, it must be an array Thanks. This topic has been moved to PHP Applications. http://www.phpfreaks.com/forums/index.php?topic=344127.0 Hi, I am very new to PHP and apologies if this question has already been answered in another thread.
I am trying to extract the information from one array into another when some search criteria is matched.
Here is an example array ($original):
Array ( [ 1234567 ] => Array ( [name] => john ) [ 3456 ] => Array ( [name] => johnny ) [ 45673 ] => Array ( [name] => james ) [ 987 ] => Array ( [name] => jamie ) [ 5628721 ] => Array ( [name] => Simon ))
So if I searched for the string john, jo, joh then the new array ($filtered) should be as follows:
Array ( [ 1234567 ] => Array ( [name] => john ) [ 3456 ] => Array ( [name] => johnny ))
I was trying to do this using array_search & preg_match but have been struggling.
Any help would be much appreciated!
I have a for loop which extracts info from a MySQL table, chooses something then needs to push each bit into an array: for($i = 0 ; $i < $query_report_rows ; ++$i) { $row= mysql_fetch_row($query_names); if($row[6] == 0) { $sName = $row[1]; } elseif($row[6] == 1) { $sName = $row[2]; } $name = "$row[0], $sName"; $print = nl2br($row[7]); } What i need is a multidimensional array to hold $name and $print: $name_print = array( array('name'=>$name 'print'=>$print ) ) How do i array push into such an array from the above for loop? (multi-dimensional array are a very weak point at the moment, so any pointers here would be very much appreciated) Hello all, I need to make a rotating banner system for a client. They want about 5 banners to rotate with Javascript. However they want the visitor to sort of step through each one on each refresh. So if I have 5 banners and I go to the site, I see banner 1 and then the javascript rotates through each one. When I go back to the site, they want it to start with banner 2 and then the javascript will rotate through each one. Then on and on. Go back and see banner 3, then step through again. I have a nice Javascript image slider I'd like to use. It basically just requires the images in order. Like: <img src="1.jpg"/> <img src="2.jpg"/> <img src="3.jpg"/> <img src="4.jpg"/> <img src="5.jpg"/> I've thought about it and I think the best way to do this would just be using PHP and a cookie. So when the viewer first goes to the site, PHP checks for the cookie. If it exists, it pulls the starting image #. If it doesn't, it starts at 0 and sets the cookie. As for the images part, I figured an associate array would work well. The key would be what the cookie logic is based on, and then the image HTML would be in the array. So you visit the site without a cookie it would be... 0 => <img src="1.jpg"/> 1 => <img src="2.jpg"/> 2 => <img src="3.jpg"/> 3 => <img src="4.jpg"/> 4 => <img src="5.jpg"/> Then when you go back to the site, I need the array to be re-ordered like this: 0 => <img src="2.jpg"/> 1 => <img src="3.jpg"/> 2 => <img src="4.jpg"/> 3 => <img src="5.jpg"/> 4 => <img src="1.jpg"/> What's the best way to go about this array logic? My experience with manipulating data inside arrays is rather limited. Basically I need it to say "Start with key # and then reorder array based on that" I have the following array structu Code: [Select] [0] => Array ( [id] => Array ( [$t] => http://www.google.com/mate/ ) [updated] => Array ( [$t] => 2011-08-31T11:43:05.942Z ) [category] => Array ( [0] => Array ( [scheme] => http://schemas.google.com/g/ [term] => http://schemas.google.com/contact/ ) ) [title] => Array ( [type] => text [$t] => Name ) [link] => Array ( [0] => Array ( [rel] => http://schemas.google.com/contacts/2008/rel#edit-photo [type] => image/* [href] => https://www.google.com/mate/feeds/photos/media/ ) [1] => Array ( [rel] => self [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/contacts ) [2] => Array ( [rel] => edit [type] => application/atom+xml [href] => https://www.google.com/mate/feeds/ ) ) [gd$email] => Array ( [0] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => email_address@gmail.com [primary] => true ) ) ) I am tried to display name and email address. I am using following method, can anyone tell me is there any better way? Thank u 4u help. NAME $name=( $emp_det[0]['title'][t]); $email =( $emp_det[0]['gdemail'][0][address]); I'm creating a quick survey app for my son's cub scout pack's end-of-year surveys. There are two sets of questions: those where they want the responses to be completely anonymous and those questions where we need to know who filled out the response (people volunteering for positions, etc) I'm storing the responses in the db as two separate arrays, $anon and $nonAnon $anon[0] will be an array containing all the questions: $anon[0][0] = Survey question # 1 $anon[0][1] = Survey question #2, etc. The responses will be stored as arrays and placed in $anon as the 2nd element: $anon[1][0][0] = first response, answer to the first question $anon[1][0][1] = first resopnse, answer to the 2nd question $anon[1][1][0] = 2nd response, answer to the 1st question Etc. The pack leadership is concerned that no one would be able to reconstruct which anon response belonged to whom by matching up the order of the anon answers with the non-anon answers. Therefore I'd like to shuffle at least the anon responses. The long answer would be to build a temp array using the elements in $anon[1] and then shuffle that array and then reassign it to $anon[1]. Is there a way to use shuffle directly on $anon[1] without having to build a temporary array, shuffling it, then replacing the elements of $anon[1]? I have an array created to control the down states of the my buttons in my navigation. Which is working well. This array will have quite a few strings in it before I'm done. I then want to conditionally load a CSS file for all the files in that array with the exception of two, is this possible? In plain in english I want to say If in array apart from these values then load my css file. My array (will have more values when complete) Code: [Select] $otherTitles = array('Product Selector', 'Avon Range', 'Knightsbridge Range', 'Kingston Range' ); My code to load a css file Code: [Select] <?php if (in_array($title, $otherTitles)) { ?> <link rel="stylesheet" type="text/css" href="homepage.css"/> <?php } ?> I want all titles in the otherTitles array to get this CSS file apart from two Product Selector and Avon Range. Thanks Richard I have an array $array_1 Code: [Select] ARRAY( [0] => info 1 [1] => info 2 [2] => info 3 ) and I have another array $array_2 Code: [Select] ARRAY( [0] =>thank you and welcome to what ever [1] =>the info you added * thanks for entering your info ) I want to loop though the first array and place the values into the [1] of the second array. But the tricky thing is I want it to insert were the * is. Code: [Select] foreach ($array_1 as $key => $val) { //not sure about this insert into ($array_2[1],after *, $val); } any help would be awesome. I am retrieving values in form of array from a database table and out of the I have to build multidimensional array depending upon the parent->child relationship in the same array. The result is as => Array ( => Array ( [label] => Shirt [uri] => # ) [1] => Array ( [label] => Jeans [uri] => # ) [2] => Array ( [label] => Lowers [uri] => # ) [3] => Array ( [label] => T-Shirts [uri] => # ) [4] => Array ( [label] => cotton shirt [uri] => # ) [5] => Array ( [label] => Trousers [uri] => # ) ) each is related to some parent-id. Can any body me any idea. |
