I've done a project that now needs to be changed in order to display one div if a variable is in an array and a different div if it isn't in the array.
Normally I'd just do
<?php $quartermonths = array("February","May","August","November");
if (in_array($month,$quartermonths))
{echo "quarter code in here";}
else
{echo "nonquarter code in here";}
?>
and be on my merry way, however the code I've got already contains a load of html and php code already, which doesn't like encapsulated within another PHP block (as far as I'm aware?)
e.g.
<?php $quartermonths = array("February","May","August","November");
if (in_array($month,$quartermonths))
{echo "Quarter HTML CODE
<?php quarter phpcode ?>";}
else
{echo "Non-Quarter HTML CODE
<?php non-quarter phpcode ?>";}
?>
So my question is, what is the best way to tackle this? Is it simply to do a javascript hide div A when the variable is met and hide divB when the variable isn't met, or is there a better solution?
Thanks
<?php
if (in_array($month,$quartermonths))
{ ?>
Quarter HTML CODE
<?php quarter phpcode ?>
<?php } ?>
split your html code from php code like this.
It sounds like you just want to concatenate the value of quarter phpcode. Let's say it's a single function, quarter_phpcode(). You can just do this:
{ echo "Quarter HTML CODE" . quarter_phpcode(); }

I have to add an html id tag to give some css properties inside this php code and I don't know how to do that?
<?php
//Start your session
session_start();
//Read your session (if it is set)
if (isset($_SESSION['user_login'])){
echo $_SESSION['user_login'];
}
?>
I have to add css property for that echo.
may be you want something like this -
if (isset($_SESSION['user_login']))
{
echo '<div id="YOUR-ID-HERE">'.$_SESSION['user_login'].'</div>';
}
This is simple HTML 101,
<tagname id="idValue">
Have you tried looking though w3schools
You need to enclose (wrap) your PHP output in a div.
And then give id to that div.
<div id="YOUR_CSS_ID_HERE">
<?php echo $_SESSION['user_login'];?>
</div>
Also, no need for brackets ( and ) for echo as it is a language construct, not a function.
Let's say I've got 2 files. 1 is common which loads all the design and stuff and one is index.
What I want to do is set a $ in index like this:
<?
$SubId3 = 'test';
include "../../common.php";
?>
Then in common I want to have something like
<?=$SubId3; if (empty($SubId3)) { echo 'homepage'; } ?>
I cannot seem to get this working. Meaning if I set it up this way. The index will never show "test".
What am i doing wrong here?
I want to do this since only certain files will contain the string $SubId3, to test some things on certain pages and not others (by adding $SubId3 = 'test'; to that particular file)
Note that <?= is short-hand to output something (think of <?= as <?php echo) and not to execute any other sort of logic or code.
However, it is possible to use the ternary operator this way:
<?= empty($SubId3) ? 'homepage' : $SubId3; ?>
This is basically equivalent to this:
<?php
if (empty($SubId3)) {
echo 'homepage';
}
else {
echo $SubId3;
}
?>
So the <?= short-hand should only be used to pass one simple variable or a ternary expression to it; everything else should use the common <?php tag.
Here's a test case for Alex (in the comments) because I can run the above code just fine with PHP 5.4.12, but he seems not to be able to.
common.php
<?= empty($SubId3) ? 'homepage' : $SubId3; ?>
index.php (visit this file then)
<?php
$SubId3 = 'test'; // <-- Comment this out for the "homepage" output
include 'common.php';
i think this
<?=$SubId3; if (empty($SubId3)) { echo 'homepage'; } ?>
should be
<?php $SubId3; if (empty($SubId3)) { echo 'homepage'; } ?>
<?=?> is short for <?php echo?>
This wont work:
<?=$SubId3; if (empty($SubId3)) { echo 'homepage'; } ?>
If you want to print some stuff, you have to use only the variable, in one block and the IF on another.
<?=$SubId3?>
And:
<?php if(empty($SubId3)) { echo 'homepage'; } ?>
Hope this helps...
Try
<?php
/* echo $SubId3; */
if (empty($SubId3)) {
echo 'homepage';
} else {
echo $SubId3;
}
?>
Consider using different style of coding.
In PHP you have generally three variants:
PHP code only
HTML files with just some echoes
Intermixed PHP and HTML
In first you use echo to output every single bit of the HTML.
Second means you include a PHP script at the top of your HTML file and call appropriate functions / insert text into the template. Just so you can edit your HTML separately from your PHP.
Third makes for sometimes unreadable and complex code, but is fast to write.
<?php if($something) {
while($otherthing) { ?>
<B>text=<?=$index ?></B>
<?php }} ?>
Just a food for thought.
I found the answer guys, thanks for all the help.
I needed to set it in the PrintHeader like this:
<?
include "../../common.php";
printHeader('BlogNr1', 'BlogNr2', 'BlogNr3');
?>
And the index had to look like this:
<?
include "../../common.php";
printHeader('BlogNr1', 'BlogNr2', 'BlogNr3');
?>
Somebody on skype helped me. thanks anyways guys!
Currently in the PHP file it has:
<?php if($myfooter_text){?>
<?php echo of_get_option('footer_text'); ?>
<?php } else { ?>
something else here
<?php } ?>
What I would like is for it to insert the footer text it finds using $myfooter_text but also add a link to the end of whatever has been pre filled in the footer text. I tried to use concatenation with the following:
<?php echo of_get_option('footer_text') . 'mylink; ?>
However this still just shows the predefined footer text and not the additional content. Is there a way to do this? I'm aware it could be added in the footer area of the dashboard but this isnt what i want to do.
Try it like this:
<?php echo of_get_option('footer_text'); ?> mylink
You can concatenate them as well like this or do it your way and be sure you close all the quotes:
<?php echo of_get_option('footer_text') . 'mylink'; ?>
Here's the problem, I am trying to echo a statement or an array after dynamically generated HTML, and unfortunately the thing that i want to echo goes above the HTML, is there any way to echo it after that dynamic HTML or work around?
Code:
Link 1
Link 2
if(isset($_GET["id"]) && $_GET["id"] == "do_something") {
$html = "dynamic html generate";
echo $html;
//after this im using foreach
foreach($array as $item) { echo $item . "<br />"; }
}
As I click one of these two , dynamically generated HTML shows up. Now for example I have an array:
$array = array("error1", "error2");
All the generated PHP goes above the dynamic HTML :/.
How should i fix it so that i can echo all of this array below the dynamic HTML?
Thanks
Use buffering with ob_start
ob_start();
// dynamic html code generate
$dynamic_html = ob_get_clean();
echo $dynamic_html;
// your code
echo $dynamic_html;
Sounds like you missed some closing tags (most likely </table>) in the dynamic html. Thats why the later generated echo gets displayed at the top.
Example (Note the missing closing table):
<?php
echo "<table><tr><td>TableText</td></tr>";
echo "I should be bellow the table, but going to the top.";
?>
will produce:
I should be bellow the table, but going to the top.
TableText
So I have this code that requires to be a member. Now the question is what code do I add to hide two different divs called "socialsignup" and "formwrap". Another question is can you have multiple <?php code here ?>s in different places on the same page? Much appreciated with any help.
<?PHP
require_once("./include/membersite_config.php");
if(!$fgmembersite->CheckLogin())
{
$fgmembersite->RedirectToURL("login.php");
exit;
}
?>
You can wrap multiple time of PHP tags in a page.
That's answer for your fisrt and second question.
You can check like this
<?php if($val=='socialsignup') {?>
html for the social sign up
<?php } else if ($val=='formwrap') {?>
html for formwrap
<?php }else{?>
remaining conditions
<?php } ?>
