Below is my PHP code and XML file, I have been trying with so many different echos to loop through my images in my XML file to display each image to correct product but can only display the first image to all three products.
XML code:
<my_products>
<product>
<id>1</id>
<image> csuT.jpg</image>
<name>Champion T-Shirt</name>
<price>18.00</price>
<description>
Get the perfect look to let everyone know you are a stylish fan!
</description>
</product>
<product>
<id>2</id>
<image> webBook.jpg</image>
<name>C# Programming: Analysis to Program Design</name>
<price>192.00</price>
<description>
Your hands-on guide to Microsoft Visual C# fundamentals with Visual Studio 2017
</description>
</product>
<product>
<id>3</id>
<image> calcPic.jpg</image>
<name>Calculator TI-BAII Plus 10DIG/24CASH</name>
<price>39.00</price>
<description>
Performs common math as well as various financial functions
</description>
</product>
</my_products>
PHP code:
$xml = simplexml_load_file($file);
$script_images="";
$script_products="";
$script_product_prices="";
//Loop through the products defined in the products.xml file
foreach ($xml->product as $r)
{
$script_images.="products[".($r->id)."]=\"".($r->image)."\";\n";
$script_products.="products[".($r->id)."]=\"".($r->name)."\";\n";
$script_product_prices.="product_prices[".($r->id)."]=\"".($r->price)."\";\n";
?>
<div>
<p class="lead">
<h3 class="pull-right no-top-margin"><?php echo $currency_symbol;?><?php echo $r->price;?></h3>
<h3><?php echo "<image src='csuT.jpg' 'calcPic.jpg' 'webBook.jpg'/>";?></h3>
</p>
<h3><?php echo $r->name;?></h3>
</p>
<p>
<?php echo $r->description;?>
</p>
<br/>
<?php
//If there is details link set for the product, show a Details button
if(trim($r->details_link)!="")
{
?>
<a target="_blank" href="http://<?php echo str_replace("http://","",trim($r->details_link));?>"</a>
<?php
}
?>
<a class="btn btn-xs btn-info" href="javascript:AddToCart(<?php echo $r->id;?>)">Add to Cart</a>
</div>
<hr/>
<?php
}
?>
<script>
var currency_symbol="<?php echo $currency_symbol;?>";
var products=Array();
<?php echo $script_images;?>
var product_images=Array();
<?php echo $script_products;?>
var product_prices=Array();
<?php echo $script_product_prices;?>
</script>
You just need to extract the image from the XML (the same way as done for the Javascript) and I've added a trim() to remove any spaces round the field...
<h3><?php $image = trim($r->image);
echo "<image src='$image'/>";?></h3>
Also add trim to...
$script_products.="products[".($r->id)."]=\"".($r->name)."\";\n";
What is this? :
<h3><?php echo "<image src='csuT.jpg' 'calcPic.jpg' 'webBook.jpg'/>";?></h3>
your src attribute is static and you must change it

I am using xpath for the first time to query an xml document for a value and return the corresponding name value. I have been reading numerous different sources on the topic but I can't seem to get it to output correctly. Here is my XML:
<?xml version="1.0" encoding="utf-8"?>
<books>
<book>
<name>Genesis</name>
<abrv>GEN</abrv>
<title>The First Book of Moses</title>
</book>
<book>
<name>Exodus</name>
<abrv>EXO</abrv>
<title>The Second Book of Moses</title>
</book>
<book>
<name>Leviticus</name>
<abrv>LEV</abrv>
<title>The Third Book of Moses</title>
</book>
</books>
Here is my PHP/HTML:
<?php $root = $_SERVER['DOCUMENT_ROOT'] . "/";
$bookID = 'GEN';
$xml = simplexml_load_file( $root . 'assets/xml/books.xml' ) or die( "No Page Data Found" );
$bookName = $xml->xpath( '//book[abrv="'.$bookID.'"]/name' );
?>
<article id="verseOfDay">
<div class="container">
<h2>verse of the day</h2>
<h6><?php echo $bookName; ?></h6> // Line 19
<p></p>
</div>
</article>
Finally, here is the notice that I am receiving:
NOTICE: ARRAY TO STRING CONVERSION IN /HOME/#####/MYWEBSITE.COM/ASSETS/INCLUDES/VERSEOFTHEDAY.PHP ON LINE 19
ARRAY
What am I doing wrong? In this example I am expecting it to output Genesis in the tag.
The SimpleXML xpath function returns an array of results, which will be empty if no result is found. So you need to check for that, and if you get a result, it will be at $bookName[0]. Something like this will work:
$bookNames = $xml->xpath( '//book[abrv="'.$bookID.'"]/name' );
$bookName = empty($bookNames) ? 'Not Found' : $bookNames[0];
?>
<article id="verseOfDay">
<div class="container">
<h2>verse of the day</h2>
<h6><?php echo $bookName; ?></h6>
<p></p>
</div>

This is the following PHP code I am using to print the elements into the table:
<!--Make table and print each xml element into it-->
<center>
<table border="1">
<tr>
<th>Title</th>
<th>Date</th>
<th>Description</th>
<th>Link</th>
</tr>
<?php
//Load the xml file int a variable for use in the table below.
$xml = simplexml_load_file("articles.xml");
echo("<tr>");
foreach ($xml->RecentArticles->Article as $entry)
{
$title = $entry['Title']
$date = $entry['Date'];
$description = $entry['Description'];
$link = $entry['Link'];
echo("<td>$title</td>");
echo("<td>$date</td>");
echo("<td>$description</td>");
echo("<td>$link</td>");
}
echo("</tr>");
?>
</table>
</center>
However nothing is printing into the table.. does anyone have any idea why?
You are accessing a (non-existent) attribute value rather than the node value for your content.
Access "Title" attribute value on the "Article" node:
$title = $entry['Title']
Access "Title" node value:
$title = $entry->Title
Example XML:
<RecentArticles>
<Article author="The Reddest" Title="This is what you are accessing with $entry['Title']">
<Title>This is what you should be accessing with $entry->Title</Title>
<Date>1/13/2009</Date>
<Description>Description</Description>
<Link></Link>
</Article>
</RecentArticles>
See this documentation for more information on how to access XML elements.
I am currently writing a PHP script to read all nodes of a XML file with more than three node levels (depth > 2). However I only could read accurately upto first level child.
I would highly appreciate, if you could let me know the error I have made while I am trying to read second level child nodes.

I have an Xml content that i want to modify before using the eZ Publish 5 API to create it.
I am trying to implement a Regex to modify the content.
Here is the Xml code that i have (with html entities) :
Print of Xml code http://img15.hostingpics.net/pics/453268xmlcode.jpg
I want to be able to catch empty.jpg in :
<img alt="" src="http://www.asite.org/empty.jpg" />
And replace the whole line for each occurrence by :
<custom name="my_checkbox"></custom>
Problem :
The img tag can sometimes contain other attributes like : height="15" width="12"
<img height="15" alt="" width="12" src="http://www.asite.org/empty.jpg" />
And sometimes the attributes are after the src attribute in a different order.
The aim would be :
Xml code - Aim http://img15.hostingpics.net/pics/318980xmlcodeaim.jpg
I've tried many things so far but nothing worked.
Thanks in advance for helping.
Cheers !
EDIT :
Here is an example of what i've tried so far :
/(<img [a-z = ""]* src="http:\/\/www\.asite\.org\/empty\.jpg" \/>)/g
Dealing with XML i've used an XML parser to reach the desired section.
Then we can apply a regex (~<img.*?>(?=</span)~) to select and replace the image tag with your custom tag (note that in the object received by the xml parser the html entities are replaces with their equivalent char).
This is a piece of code that emulates and handle your situation:
<?php
$xmlstr = <<<XML
<sections>
<section>
<paragraph>
<literal class="html">
<img alt="" src="http://asite.org/empty.png" /></span></span> Yes/no <br />
<img alt="" src="http://asite.org/empty.png" /></span></span> Other text/no <br />
</literal>
</paragraph>
</section>
</sections>
XML;
$sections = new SimpleXMLElement($xmlstr);
foreach ($sections->section->paragraph as $paragraph) {
$re = "~<img.*?>(?=</span)~";
$subst = "<custom name=\"my_checkbox\"></custom>";
$paragraph->literal = preg_replace($re, $subst, $paragraph->literal);
}
echo $sections->asXML();
?>
The output is:
<?xml version="1.0"?>
<sections>
<section>
<paragraph>
<literal class="html">
<custom name="my_checkbox"></custom></span></span> Yes/no <br />
<custom name="my_checkbox"></custom></span></span> Other text/no <br />
</literal>
</paragraph>
</section>
</sections>

i have an xml file. how to make dynamic xml?
<?xml version="1.0" encoding="ISO-8859-1"?>
<jukebox>
<song title="When the Levee Breaks" artist="Kansas Joe and Memphis Minnie" url="songs/levee.mp3" />
<song title="Better Leave that Stuff Alone" artist="Will Shade" url="songs/alone.mp3" />
<song title="Walk Right In" artist="Cannon's Jug Stompers" url="songs/walk.mp3" />
</jukebox>
here i have to fetch files from database. how it is possible?
I quite don't understand if you want to pull out those information from MySQL to XML or XML to HTML...
In the first case, we'll need more informations like :
Your MySQL schema
How do you extract info from there now
What did you try so far
In the second case, you can use that code :
<?php
$xml = '<?xml version="1.0" encoding="ISO-8859-1"?>
<jukebox>
<song title="When the Levee Breaks" artist="Kansas Joe and Memphis Minnie" url="songs/levee.mp3" />
<song title="Better Leave that Stuff Alone" artist="Will Shade" url="songs/alone.mp3" />
<song title="Walk Right In" artist="Cannon\'s Jug Stompers" url="songs/walk.mp3" />
</jukebox>';
$doc = new DOMDocument;
$doc->loadXML($xml);
$songs = $doc->getElementsByTagName('song');
foreach($songs as $song){
echo ''.$song->getAttribute('title').' by '.$song->getAttribute('artist').'';
}
DEMO HERE
It would depend on a number of other factors you haven't elaborated on, however given you intend on generating the file with PHP, and you've sorted out your database logic, something like this would work:
<?php foreach($songs as $song): ?>
<song title="<?php echo $song['title']; ?>"
artist="<?php echo $song['artist']; ?>"
url="<?php echo $song['url']; ?>" />
<?php endforeach; ?>
More details are really necessary to give you any more of answer though. For example, language?
