Is there a way to display 2 banners (without duplicating the same banner?)
In other words, I can’t just repeat the "echo" code, because then it can randomly select the same banner twice. Is there a way to make an array of 2 randomly selected banners?:
<?PHP
$collection = Mage::getModel('cms/block')->getCollection()
->addFieldToFilter('identifier', array('like'=>'ROMM-RFBanner_%'))
->addFieldToFilter('is_active', 1);
$blockCount = $collection->count();
echo ('<div class="footer-banner-boxes row clearfix">');
echo $this->getLayout()->createBlock('cms/block')->setBlockId('ROMM-RFBanner_'.mt_rand(1, $blockCount))->toHtml();
echo $this->getLayout()->createBlock('cms/block')->setBlockId('ROMM-RFBanner_'.mt_rand(1, $blockCount))->toHtml();
echo ('</div>'); ?>
As far as I know you can use
$collection->getSelect()->order(new Zend_Db_Expr('RAND()'));
$collection->getSelect()->limit(2);
Or with just PHP (not elegant though) you can read this in order to use $first_id = mt_rand(1,$count) and then exclude $first_id from the second call of mt_rand() by reading How to get a random value from 1~N but excluding several specific values in PHP?

I am trying to get a number value that is pulled from a mysql database to be formatted differently in a php document.
$oIteminfo = mysql_query("
SELECT Items.PartID, Items.VendorCost, Items.ProductName, Sum(Sales.AmountSold) AS SumOfAmountSold
FROM Items
LEFT JOIN Sales
ON Items.PartID = Sales.PartID
GROUP BY Items.PartID, Items.VendorCost, Items.ProductName
HAVING Items.PartID=$iPartID;
") or die(mysql_error());
while($row = mysql_fetch_array($oIteminfo))
{
ECHO "<h1>WOWAuctionSales</h1>";
ECHO "<img src=\"http://www.wowauctionsales.com/images/".$iPartID.".jpg\"height='35' width='35'>";
ECHO "<h1>".$row['ProductName']."</h1><br>";
ECHO "<B>Total Sold:</B>".$row['SumOfAmountSold']."<br>";
ECHO "<B>Vendor Price:</B>".$row['VendorCost']."<br>";
For example in one instance the result will pull the following number 162356 I want that number to be formatted to say 16g 23s 56c or 00g 00s 00c I have looked a fprintf, sprintf and printf, but they do not seem to do the trick. I have seen this formatting done before in php but I cannot seem to figure it out how to do it myself.
i can think of a dozen options here is one
//$number ="162356";
$number =$row['VendorCost'];
echo substr($number,0,2).'g '.substr($number,2,2).'s '.substr($number,4,2).'c';
Okay so, first of all, I searched through the www for this question, and I found some question related to arrays but not exactly to mine.
Okay so as you may know, paypal only allows one custom variable to be $POST but I need to gather the product id AND the quantity of the item bought. So to do this I made my custom variable into something that would get the post like (25-1,12-3,13-4) it means, the user bought 3 items(separated by commas), where the first number is the product id (then the separator '-' comes in) and the second one is the quantity. (so they're all in the same row and column)
Now my problem is displaying it from the database. I need to get the product name and details that's why I need to separate the numbers from each array as a string and fetch the data from the database for the information of the product. (I'm using an older version of php anyway, 5.2, I guess.)Now the problem is:
1.) It returns the word 'Array' (literally) so it would say like ArrayArrayArray
2.) How do I explode/separate those data so I can get it because I need the product ID to fetch some other data... I tried exploding it into array, then exploding it again but doesn't work (most likely my code is wrong?)
Here is my code: (I've already connected to the database)
$data = mysql_query("SELECT * from transactions") or die(mysql_error());
/* My table tag and headers goes here */
while($info = mysql_fetch_array( $data )) {
echo "<tr>";
echo '<td>' . $info['id'] . '</td>';
echo "<td>";
$array = $info['product_id_array'];
$explode_array = explode(",", $array);
foreach($explode_array as $explode_more){
$explode_more = explode("-", $explode_array);
$prod_id = $explode_more[0];
$quantity = $explode_more[1];
print_r($prod_id); //should echo the 25 in the array (25-1), right?
print_r($quantity);
}
echo"</td>";
echo"<tr>";
}
If only paypal would allow multiple custom variables T_T Thank you guys. Forgive me if I can't express my question very well or my language is not good, as english is not my first language :), Good day!
Your variable names are mixed up. Inside the foreach-loop, you should do something like this
foreach($explode_array as $explode_more){
$explode_even_more = explode("-", $explode_more);
$prod_id = $explode_even_more[0];
$quantity = $explode_even_more[1];
print_r($prod_id); //should echo the 25 in the array (25-1), right?
print_r($quantity);
}
Note, that $explode_more is used inside the loop and $explore_array is left as is.
Separate this in multiple tables, never store non-atomic values in 1 column.
Certainly not when they have relation with another table.
Suppose you want to know the sales from a certain product in some period.
I've been trying to figure out how to split the array and add different titles for each of the separate titles on the page, for each of the different things that this displays. However the most I can manage to do is add a comma between the numbers and words.
I would like to add selling"1st variable price"second variable" etc however I don't quite know how to do anything other than to turn this very confusing looking bunch of letters:
user name and notes 01001000013972583957ecCCany amount-w378- v west
into anything other than this:
0,100,10000,1397258395,7ec,CC,any amount-w378- v west
Also, this is what it looks like in its JSON form:
{"selling":"0","quantity":"100","price":"10000","date":"1397258395","rs_name":"7ec","contact":"CC","notes":"any amount-w378- v west"}
I just want all the information that is in there to displayed like that however I'm not quite sure how to add the titles that is in the JSON data. I also don't have access to the external site to change anything.
A little background: what I am trying to achieve is a price look-up for a game on my website from an external site. I tried to use an iframe but it was terrible; I would rather just manually display it rather than showing their site from mine - their style and my style clash terribly.
$json = file_get_contents('http://forums.zybez.net/runescape-2007-prices/api/rune+axe');
$obj = json_decode($json,true);
$blah1 = implode( $obj[0]["offers"][1]);
print_r($blah1);
If you know where it is, you should be able to just grab it and show it out?
You can use a failsafe to check if it is present with is_array() and isset() functions - see php.net docs on them.
Your print_r should give you good valid info -- try to wrap it around <pre></pre> tags before for better readability or view the source - it will be easier!
<pre><?php print_r($obj) ?></pre>
This should be your starting point, and from here you will either take the first one of your items or loop through all with
foreach ($obj as $o) { //should be $objects, not $obj
//do whatever with $o, like echo $o['price']
}
Each offers row is a table with each field separated by row:
$item = json_decode(file_get_contents('http://forums.zybez.net/runescape-2007-prices/api/rune+axe'));
while ($offer = array_shift($item[0]->offers)) {
echo "<table>" . PHP_EOL;
foreach ($offer as $field => $value) {
echo "<tr><th>$field</th><td>$value</td></tr>" . PHP_EOL;
}
echo "</table>" . PHP_EOL;
}

Im learning JQuery and php.
Is it possible to store multiple video links within variables and get php to echo one at random??
My goal is to control my own video ads on my site and I thought this would be a good idea but I dont have a clue where I should look online.
Here is what I was thinking
<?php
$advert1 = 'MyVIDEO1.mp4';
$advert2 = 'MyVideo2.mp4';
$advert3 = 'MyVideo3.mp4';
I want a code that would go here and say: randomly select one of these vars.
echo "At random one of the vars";
?>
I hope Im making sense. help?
You could make an array, like this:
$advert[] = array();
$advert[1] = 'MyVIDEO1.mp4';
$advert[2] = 'MyVIDEO2.mp4';
$advert[3] = 'MyVIDEO3.mp4';
$chosen_one = rand(1,count($advert));
echo $advert[$chosen_one];
You can also use array_rand() instead of shuffle():
<?php
$videos = array("MyVIDEO1.mp4", "MyVideo2.mp4", "MyVideo3.mp4");
echo $videos[array_rand($videos)];
?>
For embedding the video in the right way, have a look at http://www.w3schools.com/html/html_videos.asp
For a start, PHP itself won't exactly play a video. You could use it to echo out one of the URL's to a video. So, bear in mind there is a lot more to do than just select a video.
To answer your question in the code I'd recommend the following:
Try looking up PHP arrays. You want to keep all the videos in an array.
Next up, you'll want to shuffle that array. Then select the first element.
$videos = array("MyVIDEO1.mp4", "MyVideo2.mp4", "MyVideo3.mp4");
shuffle($videos);
echo $videos[0];
This is a simple solution
Place your adverts in an array
<?php
$adverts = array("advert1" => "MyVIDEO1.mp4",
"advert2" => "MyVIDEO2.mp4",
"advert3" => "MyVIDEO3.mp4");
$count = count($adverts);
$rand_advert = rand(1, $count);
echo $adverts['advert'.$rand_advert];
?>
Or alternatively if you don't want to have keys and just put the values in the array straight away
<?php
$adverts = array("MyVIDEO1.mp4",
"MyVIDEO2.mp4",
"MyVIDEO3.mp4");
shuffle($adverts);
echo $adverts[0];
?>
You have need all value in a array then find index randomly and show it.
<?php
$advert = array(
'MyVIDEO1.mp4',
'MyVideo2.mp4',
'MyVideo3.mp4'
);
$total_video = count($advert);
$total_video--; //array index starting from 0 so decrease 1
$random_index = rand(0, $total_video); //array index 0 to 2
$video_to_play = $advert[$random_index];
echo $video_to_play;
?>
I have a code that fetches and displays results using foreach function but problem is it returns a lot of results so page loading is very slow! Is there any way to break these results into pages like 1,2,3,4 & display only 10 results per page?
my code is
foreach ($results[1] as $url)
{
echo "<a href='$url'>$url</a> <br>";
$i++;
}
If the data is coming from a database, you should limit it there already with a LIMIT clause.
If you have no control over the source of the data, you can use array_slice() on $results[1] to get the section you want, based on the page-number and the number of items you want to display:
$partial_results = array_slice($results[1], ($page_number - 1) * $items_to_show, $items_to_show);
