PHP is an alien language for me. I am trying to pull some fields from WP's SQL database.. The content comes out okay but is a lot. I want to somehow put it in a HTML carousel or some slider, where data must be formatted like this:
<holder1>
<data1></data1>
<data2></data2>
<data3></data3>
</holder1>
<holder2>
<data4></data4>
<data5></data5>
<data6></data6>
</holder2>
I imagine I would have to put some for loop for i<4, do, then break into holder2.
Current script that echos the data =
while($row = mysql_fetch_array($rs)) {
echo "<div class='testimonials flexslider'><ul class='slides'><li class='testimonial flex-active-slide'><blockquote><p>" . $row['post_content'] . "</p><cite><span>" . $row['post_title'] . "</cite></span></blockquote></li></ul></div>"; }
I would like it to break after 3 <li> items each, into a seperate <div> or <article> whatever I find suitable according to the carousel I use.
You need an index variable, which echoes the beginning of the wrapper when it is divisible by 3, and the end of the wrapper when it leaves a remainder of 2 after division by 3 (and at the very end). It seems like this code would work:
$index = 0;
while($row = mysql_fetch_array($rs)) {
if ($index % 3 == 0) {
echo "<div class='testimonials flexslider'><ul class='slides'>";
}
echo "<li class='testimonial flex-active-slide'><blockquote><p>" . $row['post_content'] . "</p><cite><span>" . $row['post_title'] . "</cite></span></blockquote></li>";
if ($index % 3 == 2) {
echo "</ul></div>";
}
$index++;
}
if ($index % 3 != 2) {
echo "</ul></div>";
}
EDIT: a little bit of explanation to clarify the math. Suppose you have 10 results. Because we usually count from 0 in programming, they can be numbered 0 up to 9. This would make your structure look like this:
<holder>
<data0></data0>
<data1></data1>
<data2></data2>
</holder>
<holder>
<data3></data3>
<data4></data4>
<data5></data5>
</holder>
<holder>
<data6></data6>
<data7></data7>
<data8></data8>
</holder>
<holder>
<data9></data9>
</holder>
You see that we need a <holder> before elements 0, 3, 6 and 9 - all numbers which are divisible by 3. Mathematically, this is expressed with help of the remainder function - a number is divisible by 3 when its remainder after dividing by 3 is zero.
Likewise, we need a </holder> after elements 2, 5 and 8 - numbers which after division by 3 leave a remainder of 2.
We need to take care of the situation where the last block is not complete; that's why there's an extra block of code to take care of the last </holder>.

I have this array, I want to make conditional action based on the items hierarchy in the array. I'm going to compare between items based on their hierarchy and it will result a 2 dimensional array like this.
The comparison is : Imagine that there are 3 stair, in the highest stair is 5, the second stair is 3 and the last stair is 1.
If a number compared with the 1st lower floor then it'll be 3 and if a number compared with the 2nd lower floor then it'll be 5. Example : if 5 is compared with 3 then it'll be 3, if 5 is compared with 1 then it'll be 5. If a number compared with the 1st upper floor then it'll be 1/3 and if a number compared with the 2nd upper floor then it'll be 1/5. Example if 1 is compared with 3 then it'll be 1/3 and if 1 is compared with 5 then it'll be 1/5. And if 3 is compared with 5 then it'll be 1/3 and if 3 is compared with 1 then it'll be 3.
So far, this is my code
$weightvalue = array(5,3,1);
$numbers = count($weightvalue);
for ($row = 0; $row < $numbers; $row++) {
for ($column = 0; $column < $numbers; $column++) {
echo "$weightvalue[$row],$weightvalue[$column] ";
if ($weightvalue[$row]==$weightvalue[$column]) {echo "1";}
elseif ($weightvalue[$row]<$weightvalue[$column]) {echo "1/3";}
elseif ($weightvalue[$row]<$weightvalue[$column]) {echo "1/5";}
elseif ($weightvalue[$row]>$weightvalue[$column]) {echo "3";}
elseif ($weightvalue[$row]>$weightvalue[$column]) {echo "5";}
else {echo "false";};
echo ("\n");
}
}
So far this is the result, but there're some mistakes, I know what causes this but I don't know how to fix it. Please help, any suggestion will very much appreciated.
I am adding in feed Ads to my website. I have a foreach statement that creates a list of posts. I have created a counter that is supposed to count every four posts and insert the Ad content then repeat.
I have tried some other iterations of this but this is the one I can actually get to do something. I can find a lot of info on this exact thing pertaining to wordpress. But I am running cake php and would prefer a pure php solution.
<?php
$count = 1;
foreach($stories as $story) {
echo '<h2>'.$story->title.'</h2>';
if(!empty($story->excerpt)) {
echo $story->excerpt;
} else {
echo limit_text($story->body);
}
if ($count % 4 == 1) {
echo AD_SENSE_INFEED;
}
}
$count++;
?>
This code is what I currently have but its not working the way I would like it to. As if now it basically goes every other. So POST, AD, POST AD...etc.
Your problem isn't a coding problem, its a math problem. What you're using is called modulos or remainders basically.
So that said:
if ($count % 4 == 1) {
For it to equal 1 we have to feed in something that goes in evenly once and leaves one more.
What you want to do is:
if ($count % 4 == 0) {
Aka it means there's no remainder, 4 goes into it evenly with nothing left over.
As #RiggsFolly mentioned and I completely missed this(Give his comment a up vote) your $count variable should be incremented inside the loop as well otherwise it will only increment once after the loop ends.
You can get rid of count all together (and just use the numeric index of the array)
//just some "test" data
$stories = array_fill(0, 100, []);
foreach( $stories as $count => $story) {
echo $count." ".($count % 4)."\n";
if ($count % 4 == 3) {
echo "--------------------------------------\n";
}
}
Output:
0 0
1 1
2 2
3 3
--------------------------------------
4 0
5 1
6 2
7 3
--------------------------------------

If your not sure if the keys are in proper order, you can reset them:
foreach(array_values($stories) as $count => $story) {
Obviously an array starts at 0, so you have to offset the % result a bit ... lol ... Yes I am to lazy to increment.
I'm trying to build a little program to automatize a little task; in it, one can write two values (as inputs in a form) and then, in another page, numbers will be written in rows and columns with all the numbers within the range given.
The thing is... There will (almost always) be 500 numbers in the range, so I want the result to be displayed in 10 columns of 50 rows each, something like this image:
I wanted the result page (the one with all the numbers) to THEN give the possibility to export this as xml or pdf, but that's another story..
By now, I just would like to get the display right.
I'm using HTML and PHP on XAMPP. I've been able to get the first column... but can't get to the generations of the others, like this (and so on until 50):
So far, this is what I have, I'll put here my PHP code, because I don't think the HTML is relevant (but will post it too if it's needed) - (The values are passed by POST method)
<?php
$cont = 0;
$i = 0;
$arrayValues = range($valueFrom, $valueTo);
if($cont <= 50){
echo "<tr>";
for($i = 0; $i < 50; $i++){
echo "<p>$arrayValues[$i]</p>";
$cont++;
}
echo "</tr>";
}
?>
Also, using something like this --> Use PHP to Generate HTML table with static Cell Count of MySQL Data and worked ok, but I would the numbers displayed in columns... so not in rows (horizontally), so..
YES | NO
1 4 7 | 1 2 3
2 5 8 | 4 5 6
3 6 9 | 7 8 9
That's why I stopped trying with tables and just used a tag for the result.
EDIT:
So, given the "start" value and "end" value for a range, I would like to be able to print all those values in 10 columns of 50 rows each (so when it reaches 50 rows in the first column, it automatically moves to a new column and so on), and vertically (like the little diagram I tried to put above this, in the "YES" side)
Any ideas or guidance will be appreciated! :)
Have a nice rest of the week!
You can do this by splitting your range up into chunks and indexing into the resulting array of columns in a nested loop.
<table>
<?php
$valueFrom = 1;
$valueTo = 500;
$rowCount = 50;
$columns = array_chunk(range($valueFrom, $valueTo), $rowCount);
$columnCount = count($columns);
for ($row = 0; $row < $rowCount; $row++) {
echo '<tr>';
for ($column = 0; $column < $columnCount; $column++) {
$number = $columns[$column][$row] ?? '';
echo "<td>$number</td>";
}
echo '</tr>';
}
?>
</table>
I'm pretty new to PHP but I have built some fairly simple WordPress themes in my time. I'm trying to make something unique and I'm not sure how to accomplish it (or if it's even possible).
My goal is to create a loop that will dynamically close rows when it reaches the column "12" count for bootstrap (IE: col-md-3 + col-md-3 + col-md-6 = 12). The look I'm ultimately trying to achieve and how I currently have my static file set up => https://jsfiddle.net/y2mLr3hd/7/embedded/result/. I'm only using "display: flex;" for right now to just demonstrate what I'm trying to achieve. I'd like it be just rows rather than a single row.
I'm use to the standard loop for WordPress using ULs and LIs but I have no idea on how to go about what I'm trying to do. I'd like the loop to figure a random number for the column size consisting of the column sizes "3, 4, 6, 8" and create rows with columns sizes equaling "12" like I stated before. THAT or find a way on how to make it work with the way I currently have it set up.
This is the closest thing to what I'm looking for but really isn't even that close =>https://stackoverflow.com/questions/16427962/twitter-bootstrap-spans-in-dynamic-websites#=. Here's the code from that link for quick reference:
$i=0;
foreach ($posts as $post):
if ($i%2==0) echo '<div class="row-fluid">';
echo '<div class="span6">'. $post->content .'</div>';
if ($i%2==1) echo '</div>';
$i++;
endforeach;
Any help on how I might be able to go about this would be GREATLY appreciated!
There are two parts to your question:
How to divide 12 in random parts using 3, 4, 6, and 8
Given an array of numbers that add up to 12, how to generate a row with posts?
The first one is more a mathematics question. Note that you can only combine 3s and 6s, or 4s and 8s. You cannot combine 3 and 4, and still get 12.
We'll devise a simple algorithm with this in mind:
function getRandomNumbers()
{
// We start with an empty array and add numbers until we hit 12.
$result = array();
// We choose either 3 or 4 as basic number.
$x = mt_rand(3, 4);
// Now, as long as we don't hit 12, we iterate through a loop,
// adding either the basic number, or 2 times the basic number:
while (array_sum($result) < 12) {
// Randomly decide
if (mt_rand(0, 1) > 0) {
$newElement = 2 * $x; // This is either 6 or 8
// However, always make sure not to exceed 12:
if (array_sum($result) + $newElement > 12) {
$newElement = $x;
}
} else {
$newElement = $x; // This is either 3 or 4
}
// Add the new number to the array:
$result[] = $newElement;
}
// Return the resulting array
return $result;
}
Now we need to use these arrays to create rows. We start by generating an array with random numbers with the function we wrote.
We'll simply iterate through the posts, use the numbers in the array until there's none left. We'll generate a new array with random numbers whenever we need a new one. Since that means we have added 12 width-worth of columns, that's the point where we need to start a new row as well.
// Get the initial array with random numbers
$randomArray = getRandomNumbers();
// Open the initial row.
echo '<div>';
foreach ($posts as $post):
if (count($randomArray) < 1) {
// Close the row and start a new one:
echo '</div><div>';
// Get a fresh array with random numbers:
$randomArray = getRandomNumbers();
}
$nextRandomNumber = array_pop($randomArray); // This takes the next number.
echo '<div class="col-md-' . $nextRandomNumber . '">'. $post->content .'</div>';
endforeach;
echo '</div>'; // Close the final row.
I have this logic written that loops out an array into <li>
and gives #1 and every 5th a class of "alpha".
$count = 0;
foreach($gallery->data as $row){
if ($count==0 || $count%4==0) {
echo '<li class="alpha"></li>'.PHP_EOL;
} else {
echo '<li></li>'.PHP_EOL;
}
$count++;
}
I need to add to this and get the code adding a class of "omega" to every 4th <li>
You do realize that as you describe it, there will be some overlap right? (example - item 30 is both a '5th' and a '6th') Brian gave you an answer for exactly what you described, but I'm not sure if its what you want. You want ALPHA, x, x, x, OMEGA, ALPHA, x, x, x, OMEGA, ALPHA.....
You seem to want Alpha on the 5*k + 1, and Omega on 5*k
conditions:
alpha - ($count + 1) % 5 == 1
omega - ($count + 1) % 5 == 0
I think grouping in the addition makes this easier to understand, since you're count starts at 0 but you seem to be thinking in terms of beginning at 1. If you don't like that, lose the addition and change the equivalences to 0 and 4, respectively - $count % 5 == 0 and $count % 5 == 4
i know this is better suited for a comment under the last answer, but I don't see how. Am i not allowed until my reputation is higher or am i just missing something?>
right now as it stands your code adds the "alpha" class to every fourth item beginning with the first, not every fifth. In other words, items 1, 5, 9, 13, etc. will have a class of "alpha" since your counter begins at 0.
I assume that you want to add the "omega" class then to items 4, 8, 12, etc. Here's what you need to do that:
$count = 0;
foreach($gallery->data as $row){
if ($count%4==0) {
echo '<li class="alpha"></li>'.PHP_EOL;
}
else if ($count%4==3) {
echo '<li class="omega"></li>'.PHP_EOL;
}
else {
echo '<li></li>'.PHP_EOL;
}
$count++;
}
