I have the following html code:
<div class="media row-fluid">
<div class="span3">
<div class="widget">
<div class="well">
<div class="view">
<img src="img/demo/media/1.png" alt="" />
</div>
<div class="item-info">
Title 1
<p>Info.</p>
<p class="item-buttons">
<i class="icon-pencil"></i>
<i class="icon-trash"></i>
</p>
</div>
</div>
</div>
<div class="widget">
<div class="well">
<div class="view">
<img src="img/demo/media/2.png" alt="" />
</div>
<div class="item-info">
This is another title
<p>Some info and details go here.</p>
<p class="item-buttons">
<i class="icon-pencil"></i>
<i class="icon-trash"></i>
</p>
</div>
</div>
</div>
</div>
Which basically alternates between a span class with the widget class, and then the widget class without the span3 class.
What I wanted to know was if there was a way to have php "echo" or populate the details for and details under the "item-info" class. Would I need to use a foreach statement to get this done? I would be storing the information in a mysql database, and while I can get it to fill in the info one by one (repeatedly entering the and echoing out each image and item title) it's not practical when the content needed to be displayed is over 15 different items. I'm not well versed in foreach statements so I could definitely use some help on it.
If someone could help me perhaps structure a php script so that it can automatically output the html based on the number individual items in the database, that'd be greatly appreciated!
I'm wondering if the html + php (not including the foreach) would look like this:
<div class="span3">
<div class="widget">
<div class="well">
<div class="view">
<img src="img/<? $file ?>" alt="" />
</div>
<div class="item-info">
<?$title?>
<p>Info.</p>
<p class="item-buttons">
<i class="icon-pencil"></i>
<i class="icon-trash"></i>
</p>
</div>
</div>
</div>
EDIT:
I wanted to add some more information. The items populated would be based on a type of subscription - which will be managed by a group id.
I was initially going to use <? (if $_SESSION['group_id']==1)>
echo <div class="item-info">
$title
<p>$info</p>
</div>
so that only the subscribed items would populate. But, I would need it to iterate through all the items for group1 table and list it. Currently I know that I can do
<? (if $_SESSION['group_id']==1)
while ($row=mysql_fetch_assoc($sqlItem))
{
$itemInfo = $row['info'];
$image = $row['image'];
$title = $row['title'];
$url = $row['url'];
};
>
$sqlItem for now can only be assigned one thing (manually - as in: $sqlItem = '123'), unless I iterate through which is what I'm trying to figure out.
Just read that 'mysql_fetch_assoc' is being depreciated with 5.5, here is the new way and looks better, easier I think.. Hope this helps, was updated today.
I hope this helps http://php.net/manual/en/mysqli-stmt.fetch.php
replace the printf with echo '//then your html stuff
This will iterate through the rows in your database until their are no more matching records.
shouldn't a while be enough? It depends on the structure of your database and website (we didn't need so much HTML I think. Some more PHP maybe). Hope this helps.

Actually I am beginner programmer in HTML, CSS and PHP. I have simple website for add and register in courses. The user should be add course into website and the courses should be posted on the site.so users can browse and register.
Actually my problem is how to call the course name from database and how to format it with HTML code as I want.
This is the page of courses which is content the list of available courses in website ( please note it is only HTML code, I do that to see how the page will be )
Screenshot of page:
So as you see, the first page include many this HTML code to add course list into website with the following code:
<div class="card card-1">
<a href="http://127.0.0.1/project2/course details/course1.php">
<img src="http://127.0.0.1/project2/icons/coursepic.jpg" alt="Avatar" style="width:101% "></a> <div class="container">
<h4 class="textstyle"><b>Operating System</b> </h4>
<p class="textstyle">Free Course</p>
</div>
</div>
what i want do with PHP?
I want to write a PHP code to replace the P and h4 with the course name, cost of courses from my database for each available course.
Please note: the pic for each course it will be from my pc, no need to call the pic from database.
I tried to write PHP code like below:
<div>
<div class="card card-1">
<a href="http://127.0.0.1/project2/course details/course1.php">
<img src="http://127.0.0.1/project2/icons/coursepic.jpg" alt="Avatar" style="width:101% "></a> <div class="container">
<?php
include_once("db.php");
$result = mysqli_query(OpenCon(), "SELECT Course_Name,cost FROM `course`");
//while($res = mysql_fetch_array($result)) { // mysql_fetch_array is deprecated, we need to use mysqli_fetch_array
while($res = mysqli_fetch_array($result)) {
echo "<p>".$res['Course_Name']."</p>";
echo "<p>".$res['cost']."</p>";
}
?>
</div>
</div>
</div>
This is my result:
It's okay but I want the style to be like the first screenshot. each course should have picture.
After that when the user click on course name. I want move to another page which is content the course details ( for the same course that user clicked ) also it's called for my database
like this:
I hope any one help my to solve this problem only, I should solve this problem within 2 days only. and sorry if my explanation is bad.
Thanks in advance for everyone.
Put the code in a PHP loop.....
So, this
<div class="card card-1">
<a href="http://127.0.0.1/project2/course details/course1.php">
<img src="http://127.0.0.1/project2/icons/coursepic.jpg" alt="Avatar" style="width:101% ">
</a>
<div class="container">
<h4 class="textstyle"><b>Operating System</b> </h4>
<p class="textstyle">Free Course</p>
</div>
</div>
Becomes (after cleaning up the code a bit - I think you didn't mean to use two <p> in there, but I left them so you can see it. Note that using different lines for the segments makes it a lot easier to see what you have.)
include_once("db.php");
$result = mysqli_query(OpenCon(), "SELECT Course_Name,cost FROM `course`");
$count = 0;
while($res = mysqli_fetch_array($result)) {
$count ++;
// NOTE: Here is the LOOP! - not outside the query, but INSIDE it
// First you 'jump out' of PHP, going back to HTML
?> <!-- now you are in HTML (when you need PHP again, you 'jump in' and 'jump out' as needed - see the code below....) -->
<div class="card card-<?php echo $count;?>">
<a href="http://127.0.0.1/project2/course details/course<?php echo $count;?>.php">
<img src="http://127.0.0.1/project2/icons/coursepic.jpg" alt="Avatar" style="width:101% ">
</a>
<div class="container">
<h4 class="textstyle">
<b><p><?php echo $res['Course_Name'];?></p></b>
</h4>
<p class="textstyle">
<p><?php echo $res['cost'];?></p>
</p>
</div>
</div>
<?php // we are in PHP again....
}
That should do what you asked for - though I would go a step (well, more than one...) further and make as much of this dynamic as you can.
For this I will presume that:
your database table has a column called 'id' (if it doesn't, you should have) and it relates to the course number (you could make a course number column if they don't match up, but I'm keeping it simple)
you have all your pictures labeled 'coursepicX' where the X is the course number.
We'll use 'coursepic' as a default in case there isn't a picture yet...
Now, the code is more dynamic!
include_once("db.php");
$result = mysqli_query(OpenCon(), "SELECT id,Course_Name,cost FROM `course`");
while($res = mysqli_fetch_array($result)) {
// NOTE: Here is the LOOP! - not outside the query, but INSIDE it
// First you 'jump out' of PHP, going back to HTML
?> <!-- now you are in HTML (when you need PHP again, you 'jump in' and 'jump out' as needed - see the code below....) -->
<div class="card card-<?php echo $res['id']?>">
<a href="http://127.0.0.1/project2/course details/course<?php echo $res['id']?>.php">
<?php
$pic = "http://127.0.0.1/project2/icons/coursepic.jpg";
if(file_exists("http://127.0.0.1/project2/icons/course" . $res['id'] . ".jpg") {
$pic = "http://127.0.0.1/project2/icons/course" . $res['id'] . ".jpg";
}
<img src="<?php echo $pic; ?>" alt="Avatar" style="width:101% ">
</a>
<div class="container">
<h4 class="textstyle">
<b><p><?php echo $res['Course_Name'];?></p></b>
</h4>
<p class="textstyle">
<p><?php echo $res['cost'];?></p>
</p>
</div>
</div>
<?php // we are in PHP again....
}
Note that this is the basic 'shopping cart' sort of program - you will likely use it many (many) times in your career.
Happy Coding!
I am trying to consume an Amazon Product API and I choose to search for books alone base on the user search query. However after converting the response to an array, I am having problem looping through all the result without having to specify an index.
Below is my Code:
<div class="album py-5 bg-light">
<div class="container">
<div class="row">
<?php
foreach($formattedResponse as $response) {
?>
<div class="col-md-8">
<div class="card mb-4 box-shadow">
<img class="card-img-top" data-src="" alt="Card image cap">
<div class="card-body">
<p class="card-text"></p>
<div class="d-flex justify-content-between align-items-center">
<div class="btn-group">
<button type="button" class="btn btn-sm btn-outline-secondary">Arthur: <?php echo $response['Item'][0]['ItemAttributes']['Author']; ?></button>
<button type="button" class="btn btn-sm btn-outline-secondary">Title: <?php echo $response['Item'][0]['ItemAttributes']['Title']; ?></button>
</div>
<small class="text-muted">Price: <?php echo $response['Item'][0]['ItemAttributes']['ListPrice']['FormattedPrice']; ?> </small>
</div>
</div>
</div>
</div>
<?php
}
?>
</div>
</div>
</div>
Displaying the results works perfectly, the only drawback is, it fetches only the first index of the returned book response out of the thousands present because I used $response['Item'][0] if I take away the [0] from I get an error.. Below is the result
Arthur: Harry Boone Porter
Title: The Day of Light
Price: $8.00
My Question:
The array contains [0],[1],[2] to [1000] How can I fetch all the book results in the above format instead of the first index which I am using.
Here is my Array Code Snippet: https://pasteio.com/xlsoTVWJLGBO
Seems like formatted response is the named array and does not have to be iterated with foreach loop, if I'm not mistaken, you just need to:
Pass to the view not the $formattedResponse but $formattedResponse['item'] and not to iterate through it. Lets call it $items.
$items = $formattedResponse['item'];
// pass $items to the view.
In ['item'] element you have an indexed array with numbers. So iterate through it
<?php foreach ($items as $item): ?>
... html here
<?= htmlspecialchars($item['ItemAttributes']['ListPrice']['FormattedPrice']) ?>
<?php endforeach; ?>
Do not forget to escape output for your views. Use Twig, Blade or something like Html::encode($var) from Yii. How to escape output in PHP
To make debugging of multidimensional large arrays easier install larapack/dd from composer, and add
dd($largeArray)
in any place of your code. It's like var_dump, but a lot easier to look for human being ;)
I have next html structure:
<li id="REQUIRED_ITEM_1" class="listing-post">
<a class="listing-thumb" href="blah" title="blah" data-palette-listing-image="">
<img src="REQUIRED_ITEM_2" width="75" height="75" alt="blah"> </a>
<div class="listing-detail ">
<div class="listing-title">
<div class="listing-icon hidden"></div>
blah
<div class="listing-maker">
<span class="name wrap">blah</span>
</div>
</div>
<div class="listing-date">
REQUIRED_ITEM_6
</div>
<div class="listing-price">
Sold
</div>
</div>
</li>
There are few dozens of these <li> on the same page, all with different id and content. The content that I need is marked REQUIRED_ITEM_1 - REQUIRED_ITEM_6.
I am collecting the data from these <li>s with the help of Xpath.
Here is the code I use:
foreach($xpath->query("//li[#class='listing-post']") as $link) {
$REQUIRED_ITEM_1 = $link->getAttribute('id');
$REQUIRED_ITEM_2 = $xpath->query(".//img", $link)->item(0)->getAttribute('src');
$REQUIRED_ITEM_3 = $xpath->query(".//a", $link)->item(1)->getAttribute('href');
$REQUIRED_ITEM_4 = $xpath->query(".//a", $link)->item(1)->getAttribute('title');
$REQUIRED_ITEM_5 = $xpath->query(".//a", $link)->item(2)->getAttribute('href');
$REQUIRED_ITEM_6 = $xpath->query("./div/text", $link)->item(4);
}
It works as intended for the first 5 REQUIRED_ITEMs, however it seems the code to get text contained within listing-date div (REQUIRED_ITEM_6) is wrong.
Also, is this the best way to parse my html and collect data, or is there a better approach?
Here is the xPath to get REQUIRED_ITEM_6
//li[#class='listing-post']//div[#class='listing-date']/text()
That would be little bit faster (but first version may be more safe, since it is less dependent on XML structure).
//li[#class='listing-post']/div/div[#class='listing-date']/text()
So your code must look like something like this (but you may need to adjust it little bit with your php, not sure why you used item(4)).
$REQUIRED_ITEM_6 = $xpath->query(".//div[#class='listing-date']/text()", $link)->item(0)->textContent;
I'm working on this (NSFW), I created 12 subpages but only 10 are showing in the list.
I'm not using any limit() or pagination() in the snippet nor in the panel config, I can't find where this limit is regulated. My guess is a numbering issue, because if in the panel I drag up the 11th subpage up, anything below will not be displayed.
Any clue?
php:
<section id="entries">
<ul>
<li>
<div class="line asger">
<div class="text">00</div>
<div class="text bold">Asger Carlsen</div>
</div>
</li>
<?php $n = 1; foreach($pages->children()->visible()->sortBy('date', 'asc') as $entries): ?>
<li>
<div class="line">
<div class="text">0<?php echo $n++; ?></div>
<div class="table"><div class="text bold"><?php echo kirbytext($entries->title()) ?></div></div>
<div class="text"><?php echo kirbytext($entries->kind()) ?></div>
</div>
<div class="description hidden">
<?php echo kirbytext($entries->description()) ?>
</div>
<div class="left-half">
<img class="images hidden" src="<?php echo $entries->images()->first()->url() ?>" alt="<?php echo html($entries->title()) ?>" />
</div>
</li>
<?php endforeach ?>
</ul>
</section>
Folder structure: https://www.dropbox.com/s/8gigspwup0kwqei/Screenshot%202014-09-03%2015.39.51.png?dl=0
Your folder-structure is defiantly correct. You only could try to rename 04-2001 to something like 04-foo2001 but i don`t think that this causes your issue.
I had some quite similar behavior once. It was caused by image-metadata txt's that had the same name like the page-content txt's. So maybe it would be helpful if you show us your complete folder-structure including the files/filenames.
Next idea: Are you sure you have no invalid markdown in your txt's?
PS: This should be a comment, but i’m at 49 reputation, so i’m not allowed to comment ;) cheers!
It was probably a combination of .txt name conflict plus a missing image from a page.
Good evening my fellow coders, I came here with a quest to find an answer for my whole day solution looking problem.
Why this code
<h1><?=$post["post_subject"]?></h1>
is not making my post headings link-able (aka if you click on the title, it should redirect inside of the post).
I did made function in post.php, where
function view(){
$this->post = get_first("SELECT * FROM post NATURAL JOIN user WHERE post_id='$post_id'");
}
My github for the project is Here
Thank you for your time reading this :)) I can't find the solution on my own anymore, I hope you php gods now better than me.
Update.
It was not unclear. I asked simply fair question. Why is H1 not making post TITLE clickable, where there is a href= inside.
<div class="span8">
<h1><?=$post["post_subject"]?></h1>
<p><?=$post["post_text"]?></p>
<div>
<span class="badge badge-success"><?=$post["post_created"]?></span><div class="pull-right"><span class="label">alice</span> <span class="label">story</span> <span class="label">blog</span> <span class="label">personal</span></div>
</div>
</div>
All I did was made a copy of post_index.php into posts_view.php that allows me to click on title and see the post inside.
<?foreach( $posts as $post ):?>
<div class="span8">
<h1><?=$post["post_subject"]?></h1>
<p><?=$post["post_text"]?></p>
<div>
<span class="badge badge-success"><?=$post["post_created"]?></span><div class="pull-right"><span class="label">alice</span> <span class="label">story</span> <span class="label">blog</span> <span class="label">personal</span></div>
</div>
</div>
after
<div class="span8">
<h1><?=$post["post_subject"]?></h1>
<p><?=$post["post_text"]?></p>
<div>
<span class="badge badge-success"><?=$post["post_created"]?></span><div class="pull-right"><span class="label">alice</span> <span class="label">story</span> <span class="label">blog</span> <span class="label">personal</span></div>
</div>
</div>
I changed <h1><?=$post["post_subject"]?></h1> to <h1><?=$post["post_subject"]?></h1> but there is a problem, it doesnt make the h1 clickable, but I have a href.
Yes. I found my own solution for my own question.
In fact. I had to put<h1><?=$post["post_subject"]?></h1> into post_index.php not post_view.php.
