I want to only display an item once in my PHP loop. So if there's multiple values which are the same in $item['name'], it should only display it 1 time.
This is my loop:
<?php
while ($item = $stmt->fetch(PDO::FETCH_ASSOC)) {
?>
<li>
<i class="fa fa-archive"></i>
<h5><?php echo $item['name']; ?></h5>
<h3><?php echo $item['displayname']; ?></h3>
Download
<div class="clearfix"></div>
</li>
<?php
}
?>
But I have no idea how I would hide the other items with the same name. I also can't find any info about this on Google (or I'm using the wrong search terms?). Hope someone got a suggestion for me!
$array=array();
foreach ($item['name'] as $i) {
if (!in_array($i, $array)) {
$array[] = $i;
}
}
print_r($array);
<?php
// Produce your prepared statement $stmt here...
// The list of unique item names.
$itemNames = array();
// The list of items to be displayed on screen.
$displayItems = array();
while ($item = $stmt->fetch(PDO::FETCH_ASSOC)) {
$itemName = $item['name'];
if (!in_array($itemName, $itemNames)) { // If item name not already appended to the unique names list.
// Append item name to the unique names list.
$itemNames[] = $itemName;
// Append item to the list of displayable items.
$displayItems[] = $item;
}
}
?>

Note:
I always maintain the code responsible for db data access on the upper part of the page. So, for example, if I need to fetch data from db, I save it into arrays. Later, in order to bring that data in html constructs, I work just with them, without having to mix data access commands like
while ($item = $stmt->fetch(PDO::FETCH_ASSOC)) {...}
with html code. Therefore gaining (highly) increased code readability. When you create a lot of files in this way, the advantages will become obvious.
There are also (rare) disadvantages though, like the one arised here: in order to avoid mixing the db codes with the html code, I had to apply an extra array iteration: the one for building the $displayItems array.
Otherwise, if you want to use your approach, then the solution would be:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Demo</title>
<!-- Css/Js resources -->
</head>
<body>
<ul id="items">
<?php
// Produce your prepared statement $stmt here...
// The list of unique item names.
$itemNames = array();
while ($item = $stmt->fetch(PDO::FETCH_ASSOC)) {
$name = $item['name'];
if (!in_array($name, $itemNames)) { // If item name not already appended to the unique names list.
// Append item name to the unique names list.
$itemNames[] = $name;
$displayName = $item['displayname'];
$downloadUrl = $item['downloadurl'];
?>
<li>
<i class="fa fa-archive"></i>
<h5>
<?php echo $name; ?>
</h5>
<h3>
<?php echo $displayName; ?>
</h3>
<a href="<?php echo $downloadUrl; ?>" class="btn btn-default pull-right">
Download
</a>
<div class="clearfix"></div>
</li>
<?php
}
}
?>
</ul>

Good luck.
Are you trying to do something like this? If I am understanding correctly, I think you are trying to do the same thing I was.
Other people gave you good solutions to solve your issue, but this thing is going to cost you more processing time through your app run-time.
You can use DISTINCT keyword in your sql select query so automatically you will get the name just once.

For parsing a list of articles, i have this code to parse all the articles:
while($article = $articles->fetch())
{
$date = strtotime($article['createdAt']);
$formatted_date = date("F Y",$date);
?>
<br />
<div class="news-content">
<div class="news-image">
<?php echo $article['title']; ?>
</div>
<div class="news-article">
<h3>
<span><?php $date = strtotime($article['createdAt']); echo /*date("F j",$date);*/ strftime('%e %B',$date) ?></span>
<br />
<?php echo $article['title']; ?>
</h3>
</div>
</div>
<?php
} //end while loop
?>
What i want to achieve: only the first 5 <div class="news-content">...</div> should be shown.
I know i have to do something with a for loop
but i do not know exactly how to use the for loop for this situation...
Can someone help me with that?
There are a lot of different ways to limit a loop. One possibility is to use a for loop instead of a while loop. for is often a good option if you want something to happen a specific number of times. Adding something else like fetch into the continuation condition will mean it happens up to a specific number of times.
for ($i = 0; $i < 5 && $article = $articles->fetch(); $i++) {
// output article
}
I have a site that uses query strings to retrieve the data like so:
<div id="menu-sort-dropdown" class="search-filter-item">
<p><?php echo $query_sort_title; ?></p>
<ul class="dropdown-menu">
<li>Newest</li>
<li>Oldest</li>
<li>Alphabetically</li>
</ul>
</div>
<div id="menu-category-dropdown" class="search-filter-item">
<p><?php echo $query_category_title; ?></p>
<ul class="dropdown-menu">
<li>All</li>
<li>Coaching</li>
<li>Conversation</li>
<li>Craft</li>
<li>Creativity</li>
</ul>
</div>
It works great getting the data like:
teachings/?sort=SORT_NAME_ASC
or
teachings/?category=Creativity
but I can do both like:
teachings/?category=Creativity&sort=SORT_NAME_ASC
I can't wrap my head around how to add that. If I just append the strip it will become a mess.
The following code doesn't 'duplicate' the values in the url if you keep clicking the category or sort. It's made to copy/paste and run.
// to check the values
echo '<pre>';
print_r($_GET);
echo '</pre>';
echo '<hr>';
function foo($type, $value){
$args = $_GET;
$args[$type] = $value; // prevent duplication
return http_build_query($args); // returns new query string
}
?>
SORT_DATE_LIT_ASC
<br>
SORT_NAME_ASC
<br>
Coaching
<br>
Conversation
You can also have a code to remove any of those. Add it right after the previous code (also copy/paste). Take a look:
<?php
function bar($type){
$args = $_GET;
unset($args[$type]);
return http_build_query($args); // returns new query string
}
?>
<hr>
Remove SORT
<br>
Remove CATEGORY
As for now your dropdown element do a simple action - go to provided url. If you want to select a few values then your elements should store selected value instead of open url. You can do this with for example this JS code
var menus = [];
function addElement(type, element) {
menus[type] = element;
}
The type above is number index of your menu type. For example 0 can be for sort and 1 for category - this is for ensure that you can select only one value from menu type. Now you can replace your code with something like this
<div id="menu-sort-dropdown" class="search-filter-item">
<p><?php echo $query_sort_title; ?></p>
<ul class="dropdown-menu">
<li>Newest</li>
<li>Oldest</li>
<li>Alphabetically</li>
</ul>
</div>
<div id="menu-category-dropdown" class="search-filter-item">
<p><?php echo $query_category_title; ?></p>
<ul class="dropdown-menu">
<li>All</li>
<li>Coaching</li>
<li>Conversation</li>
<li>Craft</li>
<li>Creativity</li>
</ul>
</div>
To go to the prepared URL you need to add another element like for example a button (or something else with calling openUrl function after mouse click)
<input type="button" onclick="openUrl('?')" value="Go to URL">
And the JS code for openUrl function
function openUrl(prefix) {
var url = prefix + menus.join('&');
document.location.href = url;
}

Hiding a Div using php
(6 answers)
Closed 1 year ago.
I have a foreach look that checks if user has a picture or not. If the user doesn't have the picture I want to hide a <li> tab that shows the picture.
Inside my else how do I say, for this user hide tab 2?
I tried using echo 'id="tabHeader_2" style:"visibility:hidden"; but that doesn't work. I need a reference to that tab2, don't I?
<div id="picture<?php echo $i ?>" style="display: none;">
<?php
$picture = $user->pic;
if(isset($picture))
{
// show picture.
}
else
{
// hide tab2
}
?>
</div>
Then the list of tabs:
<div class="profiles">
<div id="tabContainer">
<div class="tabs">
<ul>
<li id="tabHeader_1"> Profile </li>
<li id="tabHeader_2"> Picture </li>
</ul>
</div>
<div id="tabsContent">
<div class="tabpage" id="tabpage_1"></div>
<div class="tabpage" id="tabpage_2"></div>
</div>
<script src="<?php echo Yii::app()->theme->baseUrl; ?>/js/tabs.js"></script>
</div>
</div>
Picture of what the page looks like:
I am not 100% sure about your code, but you are using isset() which would not be correct, because you set the variable right behind that check so it will be set 100% of the time. You will want to check empty() or is_file() perhaps, depends on what is in that variable.
<!-- This display: none seems strange if you are going to show the wrapped elements -->
<div id="picture<?php echo $i ?>" style="display: none;">
<?php
$picture = $user->pic;
if(!empty($picture)) {
// show picture.
}
else {
// hide tab2
}
?>
</div>
If you put the real code, it would be easier to see how you are laying out your elements.
Do Like This :-
<div class="tabs">
<ul>
<?php
$i = 1;
foreach($yourarray as $key => $value){
if(isset($value) && $value != '')
?>
<li id="tabProfileHeader<?php echo $i;?>"> Profile </li>
<li id="tabPictureHeader<?php echo $i;?>"> Picture </li>
<?php
$i++;
}
?>
</ul>
</div>
I have this function that gets a table from another site by finding each row of that table and, providing that row isn't a duplicate, echos it to my site. I want to add my own row to the bottom though so I thought it would be as simple as just echoing
<tr><td>TEXT</td></tr>
as you can see below. But when I load the page, this row isn't added. Anyone know what the cause may be?
Here is the website if that helps.
function getStats(){
$page = file_get_html(getPageURL());
$rows = array();
echo "<table id=statsTable>";
foreach($page->find('html/body/div/div[1]/center/table/tbody/tr[1]/td/table/tbody/tr/td[2]/table/tbody/tr/') as $key=>$element) {
if(!in_array($element, $rows)){
$rows[$key]=$element;
echo $rows[$key-1];
}
}
echo "<tr><td>Viewing old updates will be added soon</td></tr></table>";
}
Main problem was in key offset, when you work with arrays it's better to use keys in this case. So in order to that I've changed the in_array to array_key_exists, because we want to check if key exists, but if you want to work with element you have to know its key.
function getStats(){
$page = file_get_html(getPageURL());
$rows = array();
echo "<table id=statsTable>";
foreach($page->find('html/body/div/div[1]/center/table/tbody/tr[1]/td/table/tbody/tr/td[2]/table/tbody/tr/') as $key => $element) {
if(!array_key_exists($key, $rows)){
$rows[$key] = $element;
/* Echo only when it exists */
if(array_key_exists($key-1, $rows)){
echo $rows[$key-1];
}
}
}
echo "<tr><td>Viewing old updates will be added soon</td></tr></table>";
}
?>

I have a list of names in a database that i want to display one by one
(also for bonus points, another column in the database is a Boolean value for if a task is completed or not. if this is true i want the css content box background to be green instead of red.)
so how can i select a name from row one, put it to a PHP variable, then select the value from the "Name" column in row 2 and put that to another PHP variable or the next item in the array?
thanks for any help!

First you need to change your SELECT query to select all of the rows that you wish to display, perhaps by taking off the LIMIT clause. Something like this;
$result=mysql_query("SELECT Name FROM CLOAS_Team");
(This will get you all of the names in your table.)
Next, you need to loop through the results you got from this query, like so;
$names = array();
while($row = mysql_fetch_assoc($result))
{
$names[] = $row['Name'];
}
This will put them into the array $names for you, which you can then work with. Instead of putting them into the array, you might want to output them immediately, perhaps like this;
while($row = mysql_fetch_assoc($result))
{ ?>
<div>
<h3>
<?php
echo $row['Name'];
?>
</h3>
</div>
<?php } ?>
However, you have many more errors in your code. Such as;
You can't just invent html elements called <h3names>
I doubt that you want to set the id attribute to 'incomplete'. An id should be unique, I expect you should be putting this in as a class (class = "incomplete")
I don't think your line header("Refresh: 60; URL=$url"); will do anything as your headers have already been sent to the page. If you want this line to work, it needs to be right at the top, BEFORE any output has been sent to the browser.
And for the bonus point, include the 'Completed' field in your query (if that is what it is called) and use this to add a style to each <div> element that you display in your loop. So your query might become;
$result=mysql_query("SELECT Name, Completed FROM CLOAS_Team");
And your loop would now be like this;
while($row = mysql_fetch_assoc($result))
{ ?>
<div style = "background-color:<?php echo $row['Completed'] == true ? 'green' : ' red'; ?>">
<h3>
<?php
echo $row['Name'];
?>
</h3>
</div>
<?php } ?>
