    array problems

    Newbie, first time ever posting. I found this script online and it works exactly as I want with the exception of sorting. On my local host it presents output in alphabetical order, but online it will not. I've tried for days to work it into an array so I could sort it, but have hit my patience wall. Can someone please show me where to insert the array and then read it back? Thanks in advance for any effort put into this topic. George dir-read-script.php
  5. Hi W3, this array-within-array should print out Students 1, 2, 3 and their averaged grades, but it's only printing out Student 3 & average, and no console errors. It works fine substituting console.log, so the problem is my innerHTML part. Thanks in advance for direction. document.addEventListener("DOMContentLoaded", function(){var grades = [[89, 77, 78], [76, 82, 81], [91, 94, 89]];var total = 0;var average = 0.0;for (var row = 0; row < grades.length; row++){ for (var col = 0; col < grades[row].length; col++){ total += grades[row][col];} average = total / grades[row].len
  6. Hi everyone. I'm trying to echo the values of an array inside HTML's <option> tag.

  8. I have "Checkbox" input with multiple values. <input type="checkbox" name="drug" value="1" /><input type="checkbox" name="drug" value="2" /><input type="checkbox" name="drug" value="3" /> I want to run through this array and alert() all the values. I'm guessing I should use Jquery's .each() command but I'm not sure how to use it. the problem is, I don't understand how to use it so I can get the key and it's value. $.each($("input[name='drug']"),function(i,v){ alert(i+": "+v);}); What am I missing in the main idea?
  9. So I have a calendar that I created using JavaScript on an HTML page but now I need to create a variable that contains an array. The array needs to be a week long to-do list. Problem 1, I try to create the variable to produce the 'to-do' list but I'm not sure how to associate the array with a week out of the month. Second, I'm not sure where to plug in the variable once I have created it in order to make it show up in the calendar. Below is the script I wrote for the calendar. And help would be appreciated. Thanks! <!doctype html> <html> <head> <meta charset="UTF-8">
  10. Hello, new here and also sorta new to PHP and all that. I'm trying to find a way to select certain checkboxes and input that data into a database. And then at times go back and view and update the database. The checkboxes may also change at times and I do not want to go add a bunch of fields into the database just to see who's all in it.

  11. I need to loop through an array, in the order that the items appear, and get both the key of the item and its value. I know I can use foreach to loop through an array but as far as I know I can choose between the key and the value of the current item but not get both. Here's an example of an array: <?php$SampleArray = array(55 => "car","2" => "house","boat" => "boat",0 => "engine",666 => "website",);?> It would work somehow like this: loop($SampleArray){ echo key . " - " value . "n";} And the result would be something like:55 - car 2 - house boat - boat 0 -

  25. I have an array full of smaller arrays. The smaller arrays contain elements, one of which is a date. (Not a timestamp, a date such as 1, 2, 3, etc.) I want to sort the small arrays within the large array in order of this date. I don't see anything in the docs for PHP on how to do this.Let me state this another way. I have an array called $eventsThisMonth.
