I know it's very easy to get the text value of a link using jQuery.
But Isn't it possible to get the text value using only PHP? Please have a look at my code:
echo '<table>'
foreach($array['data']['results']['titles'] as $data) {
$title = $data['title'];
$id= $data['id'];
$url = $data['url'];
echo '<tr>';
echo '<td>' . ''.$title.'' . '</td>';
echo '<td>' . '<a href= ' .$url . ' target="_blank" >IMDb Link</a>' . '</td>';
echo '</tr>';
}
echo '</table>';
This picture shows the output of my code
Suppose the user clicked on the Third movie - Batman: The Animated Series. How do I make my movie.php page look like this -- (image below)
The Link Text (which is $title) should be passed to the movie.php page and also the IMDb Link of the corresponding movie (which is stored in the $url variable)
The Only way I know is using $_SESSION but it won't work in this case as it will only store & pass the last value of the foreach loop
Please help me in this regard. Thanks :)
Considering $id as the row ID for the particular movie from the Database. You can use url encoding over here. Your code must be
echo '<td>' . ''.$title.'' . '</td>';
When clicked your URL will look something like.
movie.php?id=3
On your movie.php file use $id = urldecode($_GET['id']); to get the movie ID and you can fetch the relevant data from the DB again.
Let me know if you have any issues.
Try sending all info with Proper Primary key OR here is runtime solution
echo '<td>' . ''.$title.'' . '</td>';
Don't forget to urlencode the variables
each link should contain the unique filed like $id so your url should be echo '<td>' . ''.$title.'' . '</td>';
You can pass the encoded value of $id so end user cannot guess the value.In movie.php you decode the $id& show information on the basis of $id

I am new to plugin development and currently developing a custom CRUD plugin for a database.
I have created a admin page which shows all the database items in a table, and also i can add to this database. However when i try to pass a variable in the URL to edit a item from the database, i get the "sorry you are not allowed to access this page".
Currently it displays the database items in a table from a query then a for each loop, with a delete button in the row also.
<?php
foreach ($results as $results) {
echo '<tr>';
echo '<td>' .$results->id. '</td>';
echo '<td>' .$results->email. '</td>';
echo '<td><a class="button" href="' .home_url(). '/wp-admin/admin.php?page=member-management%2Fdelete_member.php?id=' .$results->id. '">Remove</a></td>';
echo '</tr>';
}
?>
The problem lies with the href here:
href="' .home_url(). '/wp-admin/admin.php?page=member-management%2Fdelete_member.php?id=' .$results->id. '"
if i replace it with :
href="' .home_url(). '/wp-admin/admin.php?page=member-management%2Fdelete_member.php'"
It works fine and goes to the page i want it to, does wordpress not allow variables passed in URL's?
Fix your variables, replacing the second $results for $result. It works the way it is, but makes your code more readable.
And more important, fix the URL, replacing the second ? with &
foreach ($results as $result) {
echo '<tr>';
echo '<td>' .$result->id. '</td>';
echo '<td>' .$result->email. '</td>';
echo '<td><a class="button" href="' .home_url(). '/wp-admin/admin.php?page=member-management%2Fdelete_member.php&id=' .$result->id. '">Remove</a></td>';
echo '</tr>';
}
I am trying to grab the ID of my link from every single one and output it to a db which i will then use to go and scrape the actual page.
So i will grab the id, curl the page link then parse the details.
So far i have my links clickable, it's just trying to get the certain part of my links that is the hard part.
I have tried $_GET['id'] but this won't work as the id's are not in that format.
Here is the way my links are set out:
download.php/1000338/The%20Rise%20and%20Fall%20of%20Legs%20Diamond%20%5B1960%5D.avi.torrent
what i want to grab is the 1000338 part but i want it to do this for every single one and ofcourse they are not the same.
Any help is very much appreciated, thanks.
$link="download.php/1000338/The%20Rise%20and%20Fall%20of%20Legs%20Diamond%20%5B1960%5D.avi.torrent";
$x=explode('/',$link);
$id=$x[1];
demo:http://codepad.viper-7.com/cWYXKe
using your code:
$rss = simplexml_load_file('RSS FEED HERE');
echo '<h1>'. $rss->channel->title . '</h1>';
foreach ($rss->channel->item as $item) {
//echo the link echo '<h2>' . $item->title . "</h2>";
//echo the date echo "<p>" . $item->pubDate . "</p>";
//echo the description echo "<p>" . $item->description . "</p>"
$x=explode('/',$item->link);
$id=$x[1];
}
then use $id any way you like
I want my hyperlinks destination to be filled by a value from my database. However, when I click the link in my app it doesn't clear the "http://localhost/videoStorageApp/" before inserting the URl value from the database.
QUESTION: How do I clear the web browser url so only the URL value form the database is used?
WHAT I AM GETTING: http://localhost/videoStorageApp/'www.sonsofanarchy.tv'
WHAT I WANT: www.sonsofanarchy.tv
CODE:
This is the line that displays the hyperlink in question, if more code is needed please ask and ill add anything else that's needed:
echo '<td> ' . $row['url'] . '</td>';
echo '<td> ' . $row['url'] . '</td>';
You are probably missing "http://" in your href attribute.
<a href="google.com">
... will take you to http://currentsite.com/maybe-a-subfolder/google.com
<a href="http://google.com">
... will take you to http://google.com
For my actual web-project, I made a tagcloud. When I click on a tag, it should be passed to the page showRecipesFromTags.php.
<form name="tagform" id="tagform" method="get" action="/showRecipesFromTags.php">
<?php
include('php/getRandomTags.php');
$tagsarr = json_decode($return4634, true);
foreach ($tagsarr['Data']['Tag'] as $key => $tag11) {
echo '<a id="seastags" href="#" onclick="document.tagform.submit()"><font size="' . rand(1,4) .'">' . $tag11['Tag_name'] . '</font> <br/></a> ';
}
?>
</form>
It can already go to this page by clicking on the href, but what I need is to pass the id of the clicked tag. The name of the tag is called Tag_name. The name is shown but I don´t know how the pass the id to the next site. The id is in my JSON array and is called Tag_id.
How can I manage this?
Why do you even need a form? Just use plain links.
Try using this in the foreach loop:
echo '<a id="seastags" href="/showRecipesFromTags.php?tagId=' .$tag11['Tag_id'] . '"><font size="' . rand(1,4) .'">' . $tag11['Tag_name'] . '</font> <br/></a> ';
Your choice are:
use a hidden field
put it in the URL
use a cookie
So... I have a mysql_fetch_array and I'm running into an issue when some of the mysql data contains single or double quotes. This is the dumbed down version of my code:
while($row=mysql_fetch_array($list)) {
echo "<tr>";
echo "<td onclick='edit_form(\"" . $row['item'] . "\");'>" . $row['item'];
echo "</td></tr>";
}
The edit_form() function is used to send the value of the current item back to the value of the input in the form so the user can then easily edit their entry and then sends an UPDATE command to mysql along with the proper primary key id (which I left out because of irrelevancy). The only issue I have is if a user puts single or double quotes into the form then it messes up the onclick attribute. Please help!! I am pretty new to php and can't figure this out. I've messed around with htmlentites() and html_entity_decode() but am still getting no where. Thank you so much!
Use htmlspecialchars on $row['item'] before inserting it in your document.
So your "dumbed-down" code should be:
while($row=mysql_fetch_array($list)) {
$item = htmlspecialchars($row['item']);
echo "<tr>";
echo "<td onclick='edit_form(\"" . $item . "\");'>" . $item;
echo "</td></tr>";
}
Try the below line instead of the original in your code and see if it works:
echo "<td onclick='edit_form(\"" . str_replace('"',""e;",$row['item']) . "\");\">" . $row['item'];
And where you would like to display the $item field, just replace it in reverse if you get "e; instead of ' " '. For example:
$qoute_free= str_replace('"e','"',$passed_value);
If you are using it in javascript, the function can be as below:
function edit_form(passed_value)
{
new_value=passed_value.replace(/"e;/g,'"');
}
I advise using json_encode. That way you don't have to worry about special cases htmlspecialchars might miss (such as newlines).
while($row=mysql_fetch_array($list)) {
echo "<tr>";
echo "<td onclick='edit_form(" . json_encode($row['item'], JSON_HEX_APOS) . ");'>" . $row['item'];
echo "</td></tr>";
}
I'm just putting the values back into my <form> (when they click on a <td>) and when they hit SUBMIT it directs the data to a different .php file that uses a MySQL UPDATE instead of an INSERT. I finally found some code that works!
$list is a mysql_query I ran at the top of the document
$item is the title of one of my columns in MySQL
while($row=mysql_fetch_array($list)){
$item = json_encode($row['item']);
$item = str_replace("'","'",$item);
echo "<td onclick='edit_form(" . $item . ");'>" . $row['item'] . "</td>";
}
Now it display's correctly in the <form> when <td> is clicked (by jQuery input.val($item)) and it shows up in the table correctly via $row['item']. I don't really understand exactly how it's working (how the encode is making it work) but I am glad it is. Crazyness!!!! Thanks for responding! and thanks for your effort!!
