On my custom Single product page, I want to link every value of pa_ontwerper to the correct page. I used this code what works if pa_ontwerper has only 1 value:
$ont = $product->get_attribute('pa_ontwerper');
echo "<a href='https://www.website.nl/attribute" . $ont . "/'>" . $ont . "</a>" ;
This results in: designer1 with link to www.website.nl/attribute/designer1/
But when pa_ontwerper has for example 2 values, the output wil show something like:
designer1,designer2 with a link to www.website.nl/attribute/designer1,designer2/
Which is wrong.
What can I change in the code to make sure both values are linked correcly?

I have a google map on this page, all markers were generated by submit postcodes. So I have the array below, loop info of each marker,
imploded as ("array", "array") format, I am trying to click on a infoWindow and display the according marker details on details.php.
The problem is everything is on the button onclick event, only a simple get on the second page.
This is working, but it is a very bad way. Because the limit to URL length and security reasons;
I would like to be able to get an array info from details.php page,
and the button onclick event trigger url looks like: details.php?marker=id
I don't know what is the best way to go about this, can someone pointing me to the right direction please?
index.php
$info = array();
foreach($stmt as $x)
{
$info[] =
"<h4>" . $x['name'] . "</h4><hr />".
"<h5>Address: </h5>" . $x['Address']."<br />" .
"<h5>Postcode: " . $x['postcode'] ."</h5><br />" .
"<button onclick='window.location.href= \\\"details.php?marker=". "<h4>" . $x['name'] . "</h4><hr />".
"<h5>Address: </h5>" . $x['address']."<br />" . "<h5>Postcode: " . $x['postcode'] ."</h5><br />" . "\\\" ' >
View Details</button>";
}
$i=' "'.implode('","', $info).'"';
details.php
echo $infomarker = $_GET['marker'];
You have to use $x['id'] insted of $x['name'] which is unique in your database and also use base64_encode() for encryption of your id "details.php?marker=".base64_encode($x['id'])."
In your details.php
$infomarker = base64_decode($_GET['marker']);
Try using AJAX to get the info from details.php and then load it into your InfoWindow.
I didn't realise how simple this was, all I need is use that id, write it inside a sql statement in details page then call any part of the statement out. Thanks everyone. Thanks to #Manjeet Barnala for encode tips.
So here is my problem.I want the id of the href which is taken dynamically to be printed in the url.
My code of category.php:
CATEGORY.PHP
while($row = mysql_fetch_assoc($result))
{
echo '<a id="' . $row['topic_id'] . '" href="category.php?id=' .
$_SESSION['id'] . '&check1=//what should i put here?">;
}
all i want is for check1 to have the id of each link seperately so if i have 3 links(depends on the database) the 2nd link will have id=2 and i want to print id=2 the next time category.php is loaded.
BUT
Notice that all id are first printed and then someone will choose one of these links.
You're already doing it in other places.
It's called concatenation - All that PHP does is output dynamically generated HTML. This means that within the quotes of your echo construct you can concatenate anywhere.
All you have to do is add it to the URL as you did with ID:
while ($row = mysql_fetch_assoc($result)) {
echo '<a id="'. $row['topic_id'] .'" href="category.php?id='. $_SESSION['id'] .'&check1='. $row['topic_id'] .'"></a>'
}
your $row['topic_id'] should be different with every iteration. the $row variable gets set to a new
This will output the same $row['topic_id'] as the id attribute of the link but it will also append it as a $_GET parameter in your category.php.
If you do not know what gets passed on in the $_GET array you could always do a print_r($_GET) anywhere in the script since $_GET always gets set (even without query params, it'll just be empty).
It could be that it is unclear to me what you're asking, it could also be that you want the actual primary key id field in which case you'll just have to swap out the last bit:
&check1=$row['topic_id']
with whatever your ID field is named, probably something along the lines of:
&check1=$row['id']
where id would be the actual id of the row in the database table.
I am building a Order form for a Client's website. One of the pages lets users choose Vehicle Spareparts by entering the quantity beside each part. I have achieved this by writing the following code
<input class="qty" type="number" name="oil-pump" min="0" max="100">
The above input attribute is added several times besides each sparepart type while changing just the name value. On clicking Submit, the user is taken to a review page with details on the spareparts ordered.
I presently have the following code in review page:
<?php
echo 'Engine Bearings: ' . $_POST['eng-bearings'];
echo 'Cylinder Heads: ' . $_POST['cyl-heads'];
echo 'Cam and Valve Train: ' . $_POST['cam-valve-train'];
echo 'Oil Pump: ' . $_POST['oil-pump'];
echo 'Oil Caps and Pipes: ' . $_POST['oil-caps-pipes'];
?>
This works well if the user has entered a value in every field. If he doesn't, then the review page has just the echo text without any quantity. Also, I don't want the quantity to apppear if the user has entered 0.
I can't figure out how to use isset() with null and OR statements to not echo text when the value entered is 0 or left blank.
Any help is appreciated. Thanks!!
This is the perfect opportunity for a function:
function print_user_input($title, $queryVar) {
if (isset($_POST[$queryVar]) && !empty($_POST[$queryVar])) {
echo $title . ': ' . $_POST[$queryVar];
}
}
Use it like so:
print_user_input('Engine Bearings', 'eng-bearings');
Echo the value conditionally. If the target data is empty, echo an empty string:
echo empty($_POST['eng-bearings']) ? '': 'Engine Bearings: ' . $_POST['eng-bearings'];
Repeat for the other post values. Information about the ternary operator (<conditional> ? <value1> : <value2>) is here.
You need to check if its set & that its not empty before printing it on a screen.
<?php
if (! empty($_POST['eng-bearings'])) {
echo 'Engine Bearings: ' . $_POST['eng-bearings'];
} else {
// whatever you wanna do here in case eng-bearings is not set or its empty
}
// Do same for other $_POST values ...
?>
I have a SQL database that PHP is getting the contents of. It gets the info from each row of a table and displays it on a web page. There is also an anchor and a hidden div containing more details from that row of the SQL table. When the use clicks the anchor the jQuery needs to detect it and show the hidden div. The problem I have is that each anchor and hidden div have a dynamic id of:
'ev_a_' . $row['id']
'ev_' . $row['id']
the jQuery I assume needs to look something like this:
$('#ev_a_')[].click(function(){
$('#ev_')[].show();
}
I'm not entirely sure how this works and I've never used dynamic ids before in jQuery. Any suggestions?
I should point out the PHP/SQL code is:
while($row = mysql_fetch_array($q_result)){
echo "<br/><b>" . $row['a'] . "</b><br/>" . $row['b'] . ", " . $row['c'] . "<br/>" . $row['d'] . "<br/><a class='ev_event_a'>More Details</a><br/><div class='ev_event'>" . $row['e'] . "</div>";
}
I would use a class instead for these links instead and set the ID in a data attribute. Depending on your needs you don't even need the ID as you can show the next element if it is already part of the DOM.
A simple example (ID not used...):
Toggle details
<div class="initially_hidden">
...
</div>
....
Toggle details
<div class="initially_hidden">
...
</div>
....
and the javascript:
$('.show_more').on('click', function(e) {
e.preventDefault();
$(this).next().slideToggle();
// if you need the ID, you can get it via $(this).data('id')
});
Ok so basically I've got a product database. members search the database by clicking on categories of their choice.
These categories are spans which all trigger a javascript (ajax) function which calls a php query to find all of the subcategories of the span just clicked.
Those subcategories are outputted in a while loop which creates more spans which also trigger the same js function which will link back to the query.
The code below shows the output of the categories displayed based on the output of the database query.
"<div id=\"div1\">";
while($row = mysql_fetch_array($result))
{
$spans++;
echo " <span id=\"$spans\"
onclick='serverconnect(\"http://localhost/dreamweaver/Website/webdev/Code structure.php\",
\"nya\")'> $row[1] </span>";
echo "<br />";
}
"</div>";
So let's say the output of this is:
HEALTH
FITNESS
EDUCATION
LEISURE
How could i pass the span names as values for the next query so that whatever span is clicked on gets its appropriate value passed to the database search?
Would i have to somehow assign the contents of each span to a variable and then pass the variable to the javascript function which would then pass it to the query?
Im out of ideas as to how to do that, or if i should do it another way.
Thanks!
Try replacing:
echo " <span id=\"$spans\"
onclick='serverconnect(\"http://localhost/dreamweaver/Website/webdev/Code structure.php
\", \"nya\")'> $row[1] </span>";
With:
echo " <span id=\"$spans\"
onclick='serverconnect(\"http://localhost/dreamweaver/Website/webdev/Code
structure.php?value=" . urlencode($row[1]) . "\", \"nya\")'> $row[1] </span>";
You may then retrieve the value in $_GET['value'] after clicking the SPAN.
Note: I added some line breaks in the text for ease of reading, don't forget to remove them.
