PHP - Array Syntax Question
Quick question,
When I run the code below I get an undefined index error for the array. If I define all the indexes I have no problem making it work correctly. I thought writing it like I did below would define the indexes as they are needed. What am I doing wrong? Thanks for looking, $call_data = array(); if($call_segment['did_digits'] == '3300'){ //Check if call was answered if($call_segment['answered'] == 'No'){ $call_data['3300']['abandoned'] ++; } else{ if(in_array($call_segment['finished_on'],$phoneroom_ext)){ $call_data['3300']['phoneroom'] ++; } elseif(in_array($call_segment['finished_on'],$anoka_ext)){ $call_data['3300']['store'] ++; } } } Similar TutorialsHi,
I'm very new to PHP, 2 days in fact, but I've done some programming in other languages. I'm trying to do something pretty basic here. I've inherited a site built on WordPress and I'm trying to override one of the php files contained in a wordpress plugin to do what I want.
I have this line:
<label>
<?php if ( ! $account_required ) echo '<small>' . __( '(optional)', 'wp-jm' ) . '</small>'; ?>
</label>
I understand what the code is doing, if condition is false, then output the HTML <small> tag, I want to add and else condition to the above, that outputs the word "required" in place of where the word optional is. So if $account_required = false then shows the optional in parenthesis as it does now, otherwise I want to show the word "required" in the parenthesis. Super simple, but just can't get the syntax quite right.
Also, can someone explain the double underscore part, specifically this: __( '(optional)', 'wp-jm' ) I understand in PHP periods are used to concatenate, but what is the leading double underscore right before the word "optional" in parenthesis? it's as if there is some function being called or referenced. The end result when the HTML is rendered is "(optional)", but what's up with the leading underscore and the reference to "wp-jm" I assume that there is some plugin or something...
Any help appreciated.
Thanks....
Edited by westside, 11 September 2014 - 05:30 PM. Code: [Select] <form action="<?= $_SERVER['PHP_SELF'] ?>" method="post"> <input type="submit" name="submit" value="Refresh" /> </form> the above works fine for a refresh button ... but does not if I replace <? with <php? I often see the colon ( : ) being used in syntax however, no amount of searching through my text books or checking php.net reveals to me exactly what this is used for, when it is used and the exact definition of it's value. Intuitively it seems to mean ' or ' but I can't be sure when || is the proper operator for 'or' Can anyone point me towards a url for a succinct explanation ? thanks VJ Hi all, new to PHP and had a syntax question. I have the following code: print "<p>{$row['comment_createdate']}; This prints out a date from my sqlquery as a database datetime. I need to format it to display "Monday June 15, 2010 5:15 pm". I'm not sure how/where to attach a date() function to the record. (If it matters, the line above is inside of a loop going through several records). This really applies to attaching functions to columns within a recordset in general. Many thanks ahead of time. I have a query: $query ="select * FROM telephone_admin where name Like ' ".$_GET['answer']." ' "; I would like to add % before and after so that the query will search for result which contains the PHP variable $_GET['answer'] before or after, but the problem is how can I add % before or after ' ".$_GET['answer']." ' within the query?? Thanks! Hi, I have an output of print_r he

I have been looking at this code most of the morning and do not have a clue what is wrong with the code. I am hoping its not a stupid mistake, can someone please help me out? thank you

I have a question about the array in this code... Quote class Model { public function getBookList() { return array( "Jungle Book" => new Book("Jungle Book", "R. Kipling", "A classic book."), "Moonwalker" => new Book("Moonwalker", "J. Walker", ""), "PHP for Dummies" => new Book("PHP for Dummies", "Some Smart Guy", "") ); } } Quote class Book { public $title; public $author; public $description; public function __construct($title, $author, $description) { $this->title = $title; $this->author = $author; $this->description = $description; } } Questions: -------------- 1.) Is it correct that in the array above, the KEY is a book name and the VALUE is an object? 2.) What is the name of the array above? TomTees Hi I'm looking something simular to this: http://cupaddon.com/index.php?site=halloffame Under the place column, it shows #1 #2 #3 for each row. How can I use php to use this on my table for each row? And please say if this question makes no sense to you. I simply want to use #1 #2 etc for each of my rows for my table. I am using a while loop for my table also. I really appreciate if anyone can help me on this, thanks very much! I am trying to convert Numbers to months from mySQL. What I current have in my db is smonth = # What I am trying to figure out is if there is a way to do an array that will convert the # to a month instead of use if $smonth = 1 echo January. Any help is greatly appreciated and thank you in advance. my php array knowledge is still basic and i can't seem to get this code to yield an answer in the form i want. i would like to be able to get at $m and $b separately so I can manipulate them. how, for example do i just print $m? Code: [Select] <?php var_dump( linear_regression(array(1, 2, 3, 4), array(1.5, 1.6, 2.1, 3.0)) ); /** * linear regression function * @param $x array x-coords * @param $y array y-coords * @returns array() m=>slope, b=>intercept */ function linear_regression($x, $y) { // calculate number points $n = count($x); // ensure both arrays of points are the same size if ($n != count($y)) { trigger_error("linear_regression(): Number of elements in coordinate arrays do not match.", E_USER_ERROR); } // calculate sums $x_sum = array_sum($x); $y_sum = array_sum($y); $xx_sum = 0; $xy_sum = 0; for($i = 0; $i < $n; $i++) { $xy_sum+=($x[$i]*$y[$i]); $xx_sum+=($x[$i]*$x[$i]); } // calculate slope $m = (($n * $xy_sum) - ($x_sum * $y_sum)) / (($n * $xx_sum) - ($x_sum * $x_sum)); // calculate intercept $b = ($y_sum - ($m * $x_sum)) / $n; return array("m"=>$m, "b"=>$b); } ?> Hi, I have an array that I've set up as a JSON feed API. The array pulls data from a MySQL query, one of the fields in the query ('description') contains text with escape characters. I'm just wondering how I change either the query to remove the escape characters (ie can you strip escape chars in MYSQL?) - or change the array to strip the escape chars?? Code: [Select] //Run query $result = mysql_query(' SELECT DATE_FORMAT(gl_date,"%d-%m-%Y")as "date", gl_venue as "venue", gl_city as "city", gl_postcode as "postcode", gl_text as "description", concat(DAYOFMONTH(gl_date), MONTHNAME(gl_date),".png") AS "imageName" FROM tg_gig_list where gl_date >= curdate() and gl_publish = 1 order by gl_date '); $array = array(); $array['gigs'] = array(); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $array['gigs'][] = $row; } $output = json_encode($array); } Basically i want to take an array of numbers let's say: Code: [Select] <? $array1=array("1","2","3","4"); ?> Now say i reprint that same array, but the 3 is missing. Code: [Select] <? $array2=array("1","2","4"); ?> How would i print what's missing from $array1 out of $array2? Sorry if this is confusing, i'll be happy to go into details if needed. Hello. I have a newbie question regarding arrays: How can I echo an element's subsequent arrays and elements? For example Code: [Select] $pers = array("Steve" => array("eyes" => "green", "age" => "43", "race" => "caucasian")); and if I echo $pers["Steve"] to make it display: green 43 caucasian. Thanks. Hey, Can someone please fix my code below? I simply want to add all values for $row[score1] in first if statement and add all values for $row[score2] in second if statement and then add them together to return final value . Code: [Select] while( $row = mysql_fetch_assoc($query)) { if($clanID==$row[clan1] && $row[score1] > $row[score2]) { $points[] = $row[score1]; } if($clanID==$row[clan2] && $row[score1] < $row[score2]) { $points[] = $row[score2]; } } return $points;. So lets say I echo the variables that I want added... Code: [Select] if($clanID==$row[clan1] && $row[score1] > $row[score2]) { $points[] = $row[score1]; echo $row['score1']."<br>"; } if($clanID==$row[clan2] && $row[score1] < $row[score2]) { $points[] = $row[score2]; echo $row['score2']."<br>"; } On page it returns as: 11 16 14 Add it together is 41 and this is what I want the output to be. Hope you understand I appreciate any help! P.S. I must be able to return final value OUTSIDE loop. Thanks.

I did notice that this will work fantastic during the post season but in regular season it's a new issue... the post season xml reads out team names likes this "Carolina Panthers" as one of the elements.. however during the regular season that gets shortened to: "CAR".
How do I get it to read the xml and change "CAR" Into "Caroline Panthers"? I have to do this for all 32 teams...
Thanks everyone!
Hey guys,
I am using a function that echos out 10 images from my database. I need to have a minimum of 4 echoed images. Some categories have less than 4 images, so I would like to have a default image(s) echoed out if the database has 4 or less images.
Does anyone know how I can do this?
Below is the code I am using now to echo out the 10 images.
Thanks in advance:
<?php
$query = mysql_query('SELECT image_id FROM images ORDER BY RAND() LIMIT 10');
$i = 0;
class myCounter3 implements Countable {
public function count() {
static $count = 0;
return ++$count;
}
}
$counter = new myCounter3;
while ($row = mysql_fetch_array($query))
{
if($i % 10 === 0)
{
}
echo '<img src="http://www.mysite.com/'.$row['image_id'].'.jpg" width="300" height="auto"/>';
$i++;
}
?>
Default Image: <img src="http://www.mysite.com/default.jpg" width="300" height="auto"/> |
