I am facing an issue where the for loop loops properly to display a table in php when Google Charts is not used and when Google Charts is implemented on the page, the table only loops twice. I know this because I've echoed the count($arr) and echo the word LOOPED. My count shows 9 but it will only loop twice.
The google chart I am using is the pie chart and when this pie chart becomes really huge, where there are many slices, this would occur. What's weird is the Google Chart isn't inside this for loop.
for ($i = 1; $i < count($arr); $i++){
print_r(count($arr));
echo "LOOPED";
$splitwords = explode("ON", ($arr[$i]));
<td>$splitwords[0]</td>
<td>$splitwords[1]</td>"; }
This is the function being called.
function retrievepieCharts(minnumber,hournumber,daynumber){
google.charts.load('current', {'packages':['corechart']});
google.charts.setOnLoadCallback(drawminuteChart);
google.charts.setOnLoadCallback(drawhourChart);
google.charts.setOnLoadCallback(drawdayChart);
function drawminuteChart() {
var data = google.visualization.arrayToDataTable([
['Timing', 'Times'],
<?php
for ($i = 0; $i < count($minuteArray); $i++) {
$firstArraywithin10mins = $minuteArray[$i];
$firstDATEtoRetrieve = $firstArraywithin10mins[0];
$firstTimingtoRetrieve1 = $firstArraywithin10mins[1];
$firstTimingtoRetrieve = $firstDATEtoRetrieve . " ". $firstTimingtoRetrieve1;
$totalCountwithin10mins = count($firstArraywithin10mins)-1;
echo "['$firstTimingtoRetrieve', $totalCountwithin10mins],";
}
echo" ]);";
?>
var mintitle = "Logon Fails > 5 within " + minnumber + " minute(s)";

This is the part where the function is being called. The $minData and $hourData is retrieved when the user clicks on the submit button through a form.
if (isset($minData) and isset($hourData)){
echo "<script type='text/javascript'>retrievepieCharts('$minData', '$hourData', '$dayData');
</script>"
;
}
This is the form which takes in the $minData and $hourData. I've tried changing the $minData and $hourData values and every time I changed it, the table loops differently. I've also tried to remove the submit button to see if that was causing the issue but the result is the same without the submit.
<form id="differencesnumber" method="POST">
<label for="mindiff">Minutes Differences</label>  
<input type="number" id="mindiff" name="mindiff" style="width:50px;" min="0"
oninput="validity.valid||(value='');"required>
<br>
<label for="hourdiff">Hours Differences</label>  
<input type="number" id="hourdiff" name="hourdiff" style="width:50px;" min="0" oninput="validity.valid||(value='');"required>

<input type="submit" value="Get PieCharts">

Anyone knows what is the bug? I've been trying to debug this for days but to no avail.
I found many examples of this getting data from a mysql query. What I want to pass back to jQuery function is parsed html content in JSON format. What I want to do is separate PHP code from my initial load of the page. I'm doing this in jQuery Mobile. I know, my description is bad, it's hard to phrase.
I get article names and links from my database and output listview in index.html. When the user clicks on an article, I'm passing the link in the URL, getting it in jQuery and trying to call a PHP file which Parses that URL. Here's ALL the code:
index.html:
<body>
<div data-role="page" id="mainNews">
<div data-role="content">
<ul id="fnews" data-role="listview"></ul>
</div>
</div>
<script src="js/getmainnews.js"></script>
</body>
getmainnews.js:
var serviceURL = "http://localhost/basket/services/";
var news;
$('#mainNews').bind('pageinit', function(event) {
getNews();
});
function getNews() {
$.getJSON(serviceURL + 'getmainnews.php', function(data) {
$('#fnews li').remove();
mainnews = data.items;
$.each(mainnews, function(index, mnews) {
$('#fnews').append('<li data-icon="false"><a style="white-space:normal;" href="newstext.html?url=http://www.basket-planet.com' + mnews.link + '">' + mnews.article + '</a></li>');
});
$('#fnews').listview('refresh');
});
}
getmainnews.php:
<?php
include 'connect_to_mysql.php';
mysql_query("SET NAMES UTF8");
$sql = mysql_query("SELECT * FROM basket_news");
$mainnews = array();
while ($r = mysql_fetch_assoc($sql)){
$mainnews[] = $r;
}
echo '{"items":'. json_encode($mainnews).'}';
?>
Everything loads fine but the next page comes up empty. Here's the next 3 files...Sorry that this is such a long topic.
newstext.html:
<body>
<div data-role="page" id="newstext">
<div data-role="content">
<div id="textcontent"></div>
</div>
</div>
</body>
newstext.js:
var serviceURL = "http://localhost/basket/services/";
$('#newstext').bind('pageshow', function(event) {
var url = getUrlVars()["url"];
$.getJSON(serviceURL + 'getnewstext.php?url='+url, displayNewsText);
});
function displayNewsText(data){
var newstext = data.item;
$('#textcontent').append(newstext);
}
function getUrlVars() {
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
And finally getnewstext.php:
<?php
include_once ('simple_html_dom.php');
$url = $_GET['url'];
$html = file_get_html(''.$url.'');
$article = $html->find('div[class=newsItem]');
$a = str_get_html(implode("\n", (array)$article));
#$a->find('div[style*=float]', 0)->outertext = '';
#$a->find('h3', 0)->outertext = '';
#$a->find('div[id=comments]', 0)->outertext = '';
#$a->find('script', 0)->outertext = '';
#$a->find('a[href*=register]', 0)->outertext = '';
#$a->find('div', 4)->outertext = '';
#$a->find('div', 6)->outertext = '';
echo '{"item":'. json_encode($a) .'}';
?>
So those are the 6 files. On the newstext.html, the URL contains the URL which I need to pass to my PHP file. I'm sure the problem is in the last three files. What am I doing wrong here? Thanks in advance!
Update: Console error fixed, but still no output on the page.
Update2: From searching around, I saw somewhere that json_encode only accepts arrays. My $a in last PHP script is content from a page containing all kinds of html tags. How can I turn this into an array? To make one key/value with the value being all that html content?
The error getUrlVars is not defined newstext.js:3 says it all. You are calling a function that is not defined anywhere. I did a quick search and you probably want this:
function getUrlVars()
{
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for(var i = 0; i < hashes.length; i++)
{
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
return vars;
}
I made a TicTacToe Game! Just for fun. It works and all, but can't tell once someone has won. I used .inArray to look for winning solutions on the current board. The idea is once a winning combination of squares is on the board, an alert will pop up ("You won Bruh"). Maybe the inArray is comparing the win arrays to the chosen elements opposed to the elements of the win arrays to the chosen elements? I'm stumped. Check out the jsfiddle if you're interested and leave a response if you've figured it out. Thanks. http://jsfiddle.net/QH6W9/7/
//UPDATE
I ended up using a magic square and checking if combinations of 3 added to 15 and implemented self teaching and basic AI using possible combinations and a MySQL db. I used a second script to let the computer play itself and build up the database. It's not the most perfect code but see for yourself..

At first glance, it looks like in
$(wins).each(function(){
var maybe = $.inArray(this,xs); //if Xs match combos win
...
}
you're checking if the array xs is found in the currently checked winning combination instead of just comparing this to xs (both 1-dimensional arrays). [Tried $.inArray(wins, xs) but it won't work.]
Could this be it?
UPDATE: this version works: http://jsfiddle.net/QH6W9/9/
I fixed your code to retrieve the ids of the X'ed fields with this:
var xs = $(".x").map(function(i, el) {
return parseInt($(el).attr('id'))
}).get(); // get ids as array
And also the detection of the win situation:
$(wins).each(function() {
var found = true;
for(var i =0; i<this.length; i++) {
found &= ($.inArray(this[i], xs) > -1);
}
if (!found) return;
alert("You Won Bruh");
var all = $(".square");
$(all).addclass('clicked'); //stops more turns
return;
});
You have a couple of issues.
First, you are putting all of the locations of .x into an array, and then seeing if that array is in the wins array.
Unfortunately, $.inArray() will only return an index if the items are the same item, not if they have matching values.
$.inArray([4,5,6], [[1,2,3], [4,5,6]]) // returns -1
var ary1 = [1,2,3];
var ary2 = [4,5,6];
$.inArray(ary2, [ary1, ary2]); // returns 1
$.inArray(ary2, [ary1, [4,5,6]]); // returns -1
Secondly, if you are at a state in the game where you have more than 3 X's, you will never match a winning position:
X O _
X X O
X O _
In this case xs will equal [1,4,5,7]. This is a winning position, but will not match any of your arrays.
There are a number of other ways to go about this. The easiest, given your wins array, is to iterate through each and check if the div at each location in the array is an X. If so, stop and declare a win.
Demo: http://jsfiddle.net/jtbowden/4BDwt/1/
Note, I cleaned up some other code in this example.
Removed the redundant clickable class, and use
.square:not(.clicked).
Replaced .click() with .on().
Removed the .square IDs and just use the div order in XOs as the location, using .eq() with the array position. IDs shouldn't start with numbers, and it is better to store data in a jQuery data attribute, like <div data-location="1">, and retrieve it with .data('location'). But, in this case, it wasn't needed as the div order tells us where it is.
Replaced $(array).each(function(){}) with $.each(array, function(){}). This is the correct way to iterate over a normal array that is not jQuery objects.
You had two problems in your program:
First, you had the following:
parseInt(number);
xs[i] = number;
xs[i] was still getting a string because parseInt() does not modify its parameter. Instead, it returns the numeric value. So I changed that code to the more compact:
xs[i] = parseInt(number);
Secondly, in your $(wins).each() loop, you were using $.inArray(), but you already have the individual array, so you really wanted to do an array subset comparison there. Since Javascript/jQuery has no built-in array subset function, I just compared each element in the array:
$(wins).each(function(){
console.log( 'template: ' + this );
var allIn = true;
for( var i=0; i<this.length; i++ ) {
console.log( this[i] );
if( $.inArray( this[i], xs ) == -1 ) allIn = false;
}
if ( allIn ){
alert("You Won Bruh");
And now it works. I only did it for X's, not for O's...I'll leave that up to you! You can see my jsfiddle solution here:
http://jsfiddle.net/HxGZE/2/
EDIT: my solution now works. See the jsfiddle for proof.
My Jquery code
function nalozi() {
var id_skupine = $('#skupina option:selected').val();
$('#artikel option').remove();
//$('#artikel').append('<option value="'+id_skupine+'">'+id_skupine+'</option>');
$.getJSON('artikli.php', {id_skupine:$('#skupina').val()}, function(data) {
$.each(data, function(index,item) {
$("#artikel").append("<option value=" + item.id + ">" + item.ime_artikla + "</option>");
});
});
}
$(document).ready(function() {
nalozi();
$('#skupina').change(function() {
nalozi();
});
});
AND PHP CODE
<?php
if(isset($_GET['id_skupine']))
{
$id_skupine = $_GET['id_skupine'];
$poizvedba = mysql_query("SELECT id,ime_artikla FROM artikli WHERE id_skupine = '$id_skupine'");
$velikost = mysql_num_rows($poizvedba);
for ($i=0;$i<$velikost;$i++)
{
$elements[]=mysql_fetch_assoc($poizvedba);
}
}
echo json_encode($elements);
?>
I don't get the values back.
Update:
You should never put variable before sanitalizing/validating/type-converting into your sql queries. If your the value you expect in query string is a number, you need to properly type-cast it like this:
$id_skupine = (int) $_GET['id_skupine'];
And if it is a string, the least you can do is to use mysql_real_escape_string function:
$str = mysql_real_escape_string($_GET['str']);
Shouldn't you be grabbing the records from db like this:
if(isset($_GET['id_skupine']))
{
$id_skupine = $_GET['id_skupine'];
$poizvedba = mysql_query("SELECT id,ime_artikla FROM artikli WHERE id_skupine = '$id_skupine'");
$velikost = mysql_num_rows($poizvedba);
while($row = mysql_fetch_assoc($poizvedba)){
$elements[] = $row['ime_artikla'];
}
}
echo json_encode($elements);
Might be your query is not returning anything
$poizvedba = mysql_query("SELECT id,ime_artikla FROM artikli WHERE id_skupine = '$id_skupine'");
Remove single quote from '$id_skupine'
Try
$poizvedba = mysql_query("SELECT id,ime_artikla FROM artikli WHERE id_skupine = '".$id_skupine."'");
