It display data perfectly...now i like to have insert empty div to include ad.
I like to display 3 blocks of elements, each block will have one big unit for ad, and 8 video elements.
please check attached picture for better understanding.
Can anyone please help me to rearrage layout as in img.
Thanks
I would have a for loop iterate 4 times, and nest a foreach loop inside it.
For the ad, you can add it in the foreach loop after throwing in the ul. Below is a rough example (I'm assuming your data is coming in through a multi-dimensional array):
$results_array = [whatever your array output consists of];
for($i = 0; $i < 4; $i++){
echo '<ul class="pic-list"><li class="ad"></li>';
foreach($results_array[$i] as $j => $item){
echo '<li class="video"></li>';
}
echo '</ul>';
}

I've got a piece of PHP code that iterates through a database lookup and each iteration adds a option to a parent select element.
I'm able to add column values from the table to the name the class of each option, which i can then refer to by using option[class*="columnvalue"]
I want to set the background color of the select element that the option belongs to.
So in short i'd like:
Parent::option[class*="xyz"]
I've seen something about the < operator but this didnt work.
echo '<select class="dropdown" name="'.$time.'-'.$group.'-'.$iteration.'-'.$new_date.'" >';
$code="";
while ($row = $result->fetch_assoc()) {
unset($firstname, $lastname);
$firstname = $row['firstname'];
$lastname = $row['lastname'];
$memberid = $row['memberid'];
$code = $row['code'];
echo '<option class="drop" value="'.$memberid.'">'.$firstname . ' ' . $lastname .'</option><option value="cancel-'.$memberid.'">Cancel</option>';
}
The following will apply to the option, but the red background only shows when the drop down menu is expanded, not when selected
option[class*="drop"]{background-color:red;}
Also tried this (which i dont believe actually is a valid operator
select < option[class*="drop"]{background-color:red;}
The proposed syntax is
select:has(option[class*="drop"]) { background-color:red; }
to select all select tags that contain option[class*="drop"] elements.
But it isn't supported by any browser yet.
Here I have code in which php echoes out the number of followers, the result is displayed under Followers wrapped in h2 tags but in the start of line i.e, under Fo, I just want to display numbers in somewhat center under followers adding several   to echo mysqli_num_rows($resultfollowers); does the work but is their any one word alternative for that rather than typing several  
<h2>Followers</h2>
<?php
$checkfollowers = "SELECT * FROM follow_user WHERE user_id='$user_id'";
$resultfollowers = mysqli_query($con,$checkfollowers);
echo mysqli_num_rows($resultfollowers);
?>
Yes. Use CSS to set a width for the container and use text-align: center; to center the text.
Visual presentation has nothing to do with MySQL or PHP.
Example with inline styles:
echo sprintf( '<p style="width: 20em; text-align:center;">%s</p>', $resultfollowers );
I have some PHP which will output a set of images.If I write it this way
foreach( $data as $inform ) {
{if (isset($inform['file1'])) {
echo '<img src="'.$inform['file1'].'"><br><br>';
}
}
It will display the 4 different images in the array $inform['file1'] with 2 line breaks in between each, but if I want to position them on the page like this
foreach( $data as $inform ) {
if ( isset( $inform['file1'] ) ) {
echo '<div style="position:absolute; top:400px;"><img src="'.$inform['file1'].'"><br><br>
</div>';
}}
Then it displays all 4 images on top of each other, but in the right location.
I've tried styling it in css and nothing works. Can anybody help a newbie learn this?
Thanks in advance.
It's nothing to do with your foreach loop. You're literally telling the images to go on top of each other, so that's what they are doing. If you would like to add spacing to the top, put a container div around the images and do a margin-top: 400px;.
Your biggest problems here are:
You haven't explained what you want to achieve, and
You are mixing in PHP which is making a relatively simply problem seem harder to solve
The styling and positioning of elements should be managed through CSS (preferably not inline CSS).
Your PHP should be:
if( count( $data ) ){
echo '<div class="file1_container">';
# If there are elements in the $data array
foreach( $data as $inform ){
if( isset( $inform['file1'] ) ){
echo '<img src="'.$inform['file1'].'" />';
}
}
echo '</div>';
}else{
# No elements in the $data array
}
Your CSS could then be something like:
.file1_container {
position:absolute;
left:0;top:400px;right:0;
text-align:center;
}
This will position a DIV containing all the images at 400px from the origin, and the IMGs within it will be on the same horizontal line, aligned to the centre of the DIV.
Your practice is bad, but if you must:
foreach($data as $inform){
if(isset($inform['file1'])) {
echo "<div><img src='{$inform['file1']}' /></div><br /><br />";
}
}
Of course, this would add two breaks after the last one as well. You cannot have multiple items in different places using the same position:absolute, since they will all be relative to the last position:relative. Regardless, you should use CSS.
#PHP
foreach($data as $inform){
if(isset($inform['file1'])) {.
echo "<div class='someClass'><img src='{$inform['file1']}' /></div";
}
}
/*CSS*/
.someClass{
margin-top:10px;
}
I want to make a long list of elements, images for example that will be added into the grid which width is span12 and every elements width should be span3, that makes 4 elements in 1 row.
The problem is, when I list all the elements or I make a php function that lists them Boostrap thinks I want to put it in one row, but I don't. I want to make a new row every 4 elements or so... I want to be able to add as many <li> as I want and not worry about where another row should be.. What should I do ?
This is what happened to me, the 5th image has wrong margin on the left side. I want to make it in the same position as images in the first row.
Screenshot here
I use this php logic to echo out pictures
$dir = "../img";
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
if (preg_match("/.jpg/", $file)) {
echo "<li class='span3'>
<a href='$dir/$file' class='thumbnail'>
<img src='$dir/$file'>
</a>
</li>
";
}
}
closedir($dh);
}
}
And I have no idea on how to post a new row each 4th picture or so.
Row is marked as <div class='row-fluid'>
That's a common problem, and I think there's no elegant solution. Consider one of these approachings.
Solution 1 Review your iteration logic
If refactoring your PHP logic is an option, try to render a row each 4 elements (I can't suggest an specific code without viewing your current logic).
EDIT
The code for a while loop could be as follows:
<?php
$count = 1;
echo '<div class="row">';
while (your_condition) {
echo '<div class="span3">your_content</div>';
if ($count % 4 == 0) {
echo '</div>';
echo '<div class="row">';
}
$count++;
}
echo '</div>';
Solution 2 Hack the fifth element's margin
Correct the margin-left of the affected elements, so you don't need to respect the native Bootstrap markup.
.thumbnails .span4:nth-child(4n+1) {
margin-left: 0;
}
Unfortunately, that code is not compatible with Internet Explorer, so maybe you'll have to find a JavaScript or jQuery solution.
Quick question. I want to change the color of an int based on the value being positive or negative, using CSS if possible.
Any ideas?
In PHP you could do this:
<span style="color: <?php echo ($var < 0 ? '#FF0000' : '#00FF00'); ?>">Some text</span>
This evaluates the variable $var, if less than zero, applies red to the style (FF0000) otherwise green (00FF00).
It depends on the language you are using. In just about any language you can set the class of the tags around the value using the dynamic part of the language. If the value doesn't have its own tags you can use <span></span> around the value to give it a class. then you just use the dynamic code to set the class.
If you are using a language like Ruby there are some CSS Selectors Gems you can use but I don't know much about them or if they will help.
I use wordpress and the table with newly posted posts and custom posts are on index.php, the code I am inserting between td tags
<td style="font-weight: <?php echo ($var <= 0 ? 'normal' : 'bold'); ?>"><?php echo get_portf_posts_count_from_last_24h(); ?></td>
I tried also this code and neither this works:
<?php
if ($output <= 0) {
$output = 'normal';
print $output;
}
else // +
{
$output = 'bold';
print $output;
}
?>
