How can i add to variable $title inside echo ? In the foreach:
<?php
foreach($this->searchfields as $fsearch) {
$title = $this->field->showFieldTitle($this->catid,$fsearch);
echo "<div id=".$fsearch->name.">".htmlspecialchars($title)."";
$this->field->showFieldSearch($fsearch,$this->catid,null);
echo "</div>";
}?>
I tried echo "<div id=".$fsearch->name.">".htmlspecialchars(<div class="header">$title</div>).""; but it doesnt work :)
How about:
echo "<div id='".$fsearch->name."'><div class='header'>".htmlspecialchars($title)."</div>";
?

how can i pass the id as the name.I used this code.
<?php
$i = 1;
foreach ($view as $row)
{
echo "<tr>";
echo "<td>".$i."</td>";
echo "<a href="<?php echo base_url();?>admin/play/songs/<?php echo $row->audio"><td>". $row->audio . "</td>";
$i++;
echo "</tr>";
}
?>
I want to play the song when user press the name of the song.but i am not able to pass the name of the song to my controller "play".so please help and this is my controller where i want to pass the data.
class Play extends CI_Controller {
public function songs($name){
$data['name'] = $name;
$this->load->view('admin/play',$data);
}
You should grab id instead of name it will make your job easier.
<?php
$i = 1;
foreach ($view as $row)
{
echo "<tr>";
echo "<td>".$i."</td>";
echo "<a href="<?php echo base_url();?>admin/play/songs/<?php echo $row->id"><td>". $row->audio . "</td>";
$i++;
echo "</tr>";
}
?>
First of all you should know that you can pass the url you want after base_url as a parament in base_url like
base_url('admin/play/songs/');
Secondly you can pass anything to controller via this method
base_url('admin/play/songs/{$row->audio}');
Just excited to know if it works
I need to do something like
$var = "Hello World ..the value is <?php echo 'XYZ' ?>";
Any help will be highly useful. I am stuck in this from the very long time but not able to acheive this. please help
Below is my PHP code that I need to assigned again to php variable (this variable will be passed to return of my ajax call)
<div class="photo-post">
<h4 class="h4-1">Some data...</h4>
<?php
$i=0;
$unique_seq="888094499";
$pic_counter=1;
foreach (glob("target/*".$unique_seq."*") as $filename)
{
$i++;
}
$total_pics=$i;
echo "<div id='post-photo-slider'>";
if($i>1)
{
echo "<a href='#' class='control_next_photo'>></a>";
echo "<a href='#' class='control_prev_photo'><</a>";
}
echo "<ul>";
foreach (glob("target/*".$unique_seq."*") as $filename)
{
echo "<li>";
echo "<div class='photos-slide-container'>";
echo "<img src='".$filename."' width='540px' height='225px'>";
echo "<span class='count-span-photos'>".$pic_counter." of ".$total_pics."</span>";
echo "</div>";
echo "</li>";
$pic_counter++;
}
if ($i==1)
{
echo "<li></li>";
}
echo "</ul>";
echo "</div><!-- post-photo-slider END -->";
echo "<hr class='hr4'>";
?>
</div><!-- photo end -->
you cannot do it in this way
$var = "Hello World ..the value is <?php echo 'XYZ' ?>";
when you return this string to your javascript php code cannot be execute on client side!!!!
why do not return do this simple way?
$var = "Hello World ..the value is " . "XYZ";
I have this code
$css=0;
<?php
echo "<div>";
function style(){
global $css;
echo $css;
}
echo "</div>";
$css =5 ; style();
?>
what i want to happen is this
<div>5</div>
and what really happens is
<div></div>5
I need to declare the value of the variable then go back and echo it in the same place it intended to be in, and I can't change the order due to many reasons in the code structure .
UPDATE :: after reading all the answers it seems i wasn't clear enough .
<html>
<?php $css=0; ?>
<div id="<?php echo $css ?>"></div>
<div id ="K"></div>
<?php
$css=5;
?>
</html>
this is the situation
1- i can not declare $css before the echo.
2- i can not reposition anything from this structure .
3- i can not put #K after the declaring of the $css .
what i really need a way to put the value inside the variable and let echo where it's .
any ideas ?
you can try this as well using js
<?php
$css=0;
echo "<div id='tt'>";
/*function style(){global $css; echo $css;}*/
echo "</div>";
$css =5 ;
echo "<script>";
echo "document.getElementById('tt').innerHTML = $css";
echo "</script>";
?>
Your function is run when you call it, and as it is called below the you get the expected 5.
To fix this:
echo "<div>";
style();
echo "</div>";
<?php
echo "<div>";
function style() {
global $css;
echo $css;
}
$css =5 ;
style();
echo "</div>";
?>
or simply:
<?php
function style() {
global $css;
echo $css;
}
$css = 5;
echo "<div>" . style() . "</div>";
?>
Previously, you well calling the function to echo out the variable after closing the div.
I'm trying to learn how to use Sessions to maintain state between pages.
I think my problem is that I dont know how to escape properly. When I load the page im not getting the SID at the end of the url, instead I'm getting this:
mytestsite.com/login.php?<?php echo SID;?>
I have session_start() at the top of every page. And the session initialy works as I see the login name appear on the page and the Register and Login links, but then when I click to another page the session is not maintained.
The main site nav is dynamically createdusing an array($nav) and foreach loop. Here too I'm not sure how to echo the url and php SID constant. I don't think my syntax is correct.
//LOGIN BAR
echo "<nav id='statusBar'>";
echo "<ul>";
if(isset($_SESSION['userIn']) && $_SESSION['userIn'] != ''){
echo "<li id='userLo'>Log Out</li>";
echo "<li id='userLi'>User Logged In: " . $_SESSION['userIn'] . "</li>";
} else{
echo '<li>Register</li>';
echo '<li>Login</li>';
}
echo "</ul>";
echo "</nav>";
//START MAIN MENU
echo "<nav id='nav'> ";
$nav = array();
$nav['index.php?<?php echo SID;?>'] = 'Home';
$nav['public1.php?<?php echo SID;?>'] = 'Public 1';
$nav['public2.php?<?php echo SID;?>'] = 'Public 2';
$nav['members.php?<?php echo SID;?>'] = 'Members';
//CREATE UNORDERED LIST
echo '<ul>';
foreach ($nav as $key => $navValues) {
echo "<li>";
echo "<a href='$key'>$navValues</a>";
echo "</li>";
}
echo '</ul>';
echo "</nav>";
Below everything within echo '..'; is interpreted as html.
echo '<li>Login</li>';
If you want to use variables inside the string you have to concatenate them like so:
echo 'Login' ;
For concatenating php code take a look at:
http://php.net/manual/en/language.operators.string.php
and more about sessions:

I am going to write following code for my blog. But problem, I am facing with:
"echo 'a href=".$query2['url']."</a>';" I want to add .$query2['url']. in echo and also want to add .html at the end of url like
"a href=".$query2['url'].html.".
If you have any idea please tell me as soon as possible thanks. Basically I am fetching this data from database .
<?php
$start=0;
$limit=5;
if(isset($_GET['id']))
{
$id=$_GET['id'];
$start=($id-1)*$limit;
}
$query=mysql_query("select * from tbl_services LIMIT $start, $limit");
echo "<div class='entry'>";
while($query2=mysql_fetch_array($query))
{
echo '<h2>' .$query2['name'].'</h2>';
echo "<p>".$query2['Contents']."</p>";
echo "<div class='meta'><i class='fa fa-clock-o'></i>".$query2['date']. "<b><i class='fa fa-user'></i></b> Written by <strong>Arslan Ali</strong> <b><i class='fa fa-comment-o'></i></b>" ;
echo "</div>";
}
echo "</div>";
$rows=mysql_num_rows(mysql_query("select * from tbl_services"));
$total=ceil($rows/$limit);
echo "<ul class='pagination'>";
if($id>1)
{
echo "<li><a href='?id=".($id-1)."' class='disabled'><<</a></li>";
}
for($i=1;$i<=$total;$i++)
{
if($i==$id) { echo "<li class='current'>".$i."</li>"; }
else { echo "<li><a href='?id=".$i."'>".$i."</a></li>"; }
}
if($id!=$total)
{
echo "<li><a href='?id=".($id+1)."' class='disabled'>>></a></li>";
}
echo "</ul>";
?>
(Updated)
Replace this line
echo '<h2>' .$query2['name'].'</h2>';
with
echo "<a href='".$query2['url'].".html'>".$query2['name']."</a>";
There is still one problem with the solution made by Syntax Error. The href is in single quotes. This is not the proper Syntax. It is easily remedied by reversing the use of the single and double quotes as I have shown here.
echo '' . $query2['name']. '';
