I'm looking for a function like and if else statement for php which will execute certain html code.
For example:
<?php>
$result = 1;
if ($result == 1)
<?>
html code
else
html code
So, based off the result variable gotten from php scripts, a certain html page is output. I've tried echoing the entire html page, but it just displays the html code-> tags and such.
Hopefully you get what I'm trying to get across, ask if you need any clarification questions. Thanks!
That should work:
<?php
$result = 1;
if($result==1) {
?>
html code
<?php
} else {
?>
html code
<?php
}
?>
The problem I'm facing with the if else statement, is in order to display the html, I have to exit php coding. Thus, the if else statement will not work. (Link)
This is not entirely true. You can use the approach below:
<?php
// Do evaluations
if ( $result == "something" )
{
?>
<p>Example HTML code</p>
<?php
} elseif ( $result == "another thing")
{
?>
<span>Different HTML code</p>
<?php
} else {
?>
<h4>Foobar.</h4>
<?php
}
// Rest of the PHP code
?>
Or, if you don't want to exit PHP coding, you can use the echo or print statements. Example:
<?php
// Evaluations
if ( $result == "foo" )
{
echo "<p>Bar.</p>";
} else {
echo "<h4>Baz</p>";
}
// Some else PHP code
?>
Just be careful with proper sequences of ' and " characters. If your HTML tags are to have arguments, you should watch your step and use either of the following approaches:
echo "<span class=\"foo\">bar</span>";
echo '<span class="foo">bar</span>";
If you want to evaluate some PHP and print the HTML results later, you could use something like this
<?php
$output = "";
if ( $result == "something" ) {
$output = '<p>Example HTML code</p>';
} else if ( $result == "another thing") {
$output = '<span>Different HTML code</p>';
} else {
$output = '<h4>Foobar.</h4>';
}
// Output wherever you like
echo $output;
?>
EDIT (because I'm not sure what you;re trying to do so i'm just putting out different ideas):
If you're trying to output an entire page, it may be useful to use header('location: newPage.html'); instead of $output. This redirects the browser to an entirely new web page. Or you can likely include newPage.html as well.
very close:
<?php
$result = 1;
if ($result == 1){
?>
html code
<?php } //close if
else {
?>
html code
<?php
} //close else
?>
you can echo html code something like this
<?php
$result = 1;
if ($result == 1){
echo "<h1>I love using PHP!</h1>";
}
?>
this would output if Result is 1
**I love using PHP!** //but slightly bigger since its H1

Goal:
Instead of showing simple YES or NO.
If value is found in record, show hyperlink with that value or else show text "No"
How to modify below code for this purpose:
<?php echo $row_RecordsetContacts['propertyFile'] ? '<strong>Yes</strong></br>' : 'No</br>'; ?>
View
</td>
<?php
$file = $row_RecordsetContacts['propertyFile']; # for readability only
if ($file)
{
?>View<?php
}
else
{
?>No<?php
}
I also suggest to avoid mixing echo and HTML markup. In 99% cases it makes the code better for understanding.
Try the following code:
<?php
$prop = $row_RecordsetContacts['propertyFile'];
if(empty($prop)) {
echo "No";
} else {
echo "<a href='propfiles/$prop'>View</a>";
}
?>
Can i use if else statement for css?
This is where i want the color of the text to change:
<?php echo $status; ?>
There will be 2 status: Pending & Delivered
Pending will be red color and delivered will be green
Can i do something like (for CSS):
.pending {text-decoration:underline; color:red;}
.delivered {text-decoration:underline; color:green;}
and if else statement:
if ($status==delivered)
{
//this is where i don't know what to do and code
}
else
{
//and here
}
What should i put there? Or any other solution?
If the $status variable in PHP actually matches your class names, just use it in your PHP when displaying whatever the thing is that's being styled:
e.g. if $status == 'pending', then:
<div class="<?= $status ?>">...</div>
will render
<div class="pending">...</div>
and match your .pending rule.
Output html with php / javascript / any other language, and assign classes to the whatever element you want.
pure PHP example:
<?php
if(true) {
echo '<div class="pending">content</div>';
} else {
echo '<div class="delivered">content</div>';
}
?>
Another way using variables (PHP + html):
<?php
if(true) {
$status = 'pending';
} else {
$status = 'delivered';
}
?>
<html>
<head>
</head>
<body>
<div class="<?php echo $status; ?>">content</div>
</body>
</html>
I was wondering if it's possible to have an if statement within an echo.
I have if statement which works fine when echoing results through the a while loop... This is the statement:
<div><?php if ($row['image'] == '') {}
else {echo "<img src='data:image/jpeg;base64,".base64_encode($row['image'])."'>";} ?>
<?php if ($row['video'] == '') {}
else {echo "<iframe src={$row['video']}></iframe>";} ?></div>`
So basically it's either a video or an image which works fine but then I implemented an infinite scroll to my blog which echoes the data from the database through and if statement like so:
if ($results) {
while($obj = $results->fetch_object())
{
echo '
<div><h3>'.$obj->headline.'</h3> </div>
<div><img src='data:image/jpeg;base64,".base64_encode('.$obj->image.')."'></div>'
So I wondering if anyone knows if it's possible to transfer that if statement within this echo so that it display an image firstly and then knows whether one is present or when a video is present within the database.
Thanks in advance for any help.
PS: I'm very new to coding/php!
Of course. Just split up the echo into multiple statements:
while($row = $results->fetch_object()) {
echo '<div>';
if ($row['image'] == '') {
} else {
echo "<img src='data:image/jpeg;base64,".base64_encode($row['image'])."'>";
}
if ($row['video'] == '') {
} else {
echo "<iframe src={$row['video']}></iframe>";
}
echo '</div>';
}
Try this one.
//first initialize a variable as a string
$result="";
while($obj = $results->fetch_object()) {
$result.="<div>";
if (!empty($obj['image'])){
$result.="<img src='data:image/jpeg;base64,".base64_encode($obj['image'])."'>";
}
elseif (!empty($obj['video'])){
$result.="<iframe src={$obj['video']}></iframe>";
}else{
//show some notification or leave it
//echo 'not Found';
}
$result.="</div>";
}
//finally you need to print the result variable.
echo $result;
I feel like I know this, but am getting frustrated that I can't remember exactly how to do this.
In PHP, I need to repeat items of a record set in a unordered list. I can repeat items fine, but I don't want anything to show if the record set is empty. Right now, if there is no record, the code is still displaying a blank list item, when I just want nothing to appear.
I have tried this:
<?php do { ?>
<li>Content Goes Here</li>
<?php } while (!feof($recordsetName) && $row_recordsetName = mysql_fetch_assoc($recordsetName)); ?>
And I have tried doing it this way by putting the repeating element withing an if/else statement like this:
<?php if (!feof($recordsetName)) {
echo ""; }
else do { ?>
<li>Content Goes Here</li>
<?php } while ($row_recordsetName = mysql_fetch_assoc($recordsetName));
; } ?>
But that isn't working either. Any information would be helpful
while($row = mysql_fetch_assoc($recordsetName)) {
if($row['fieldname'] != '') {
echo '<li>Content Goes Here</li>';
}
}
or you could check if the query was successful...
$result = mysql_query($sql);
if($result) {
echo '<li>Content Goes Here</li>';
}
or if it returned any results...
$results = mysql_fetch_assoc($recordsetName);
if(mysql_num_rows($results) > 0) {
while($row = mysql_fetch_assoc($results)) {
echo '<li>Content Goes Here</li>';
}
}
Also, you should really be using mysqli or PDO, as mysql is depreciated.
Edit: added loop in example 3.
How can I write the following statement in PHP:
If body ID = "home" then insert some html, e.g.
<h1>I am home!</h1>
Otherwise, insert this html:
<p>I'm not home.</p>
Doing it with native PHP templating:
<?php if ($bodyID==='home') { ?>
<h1>I am home!</h1>
<?php } else { ?>
<p>I'm not home!</p>
<?php } ?>
You can try using this :
$html = '';
if ( $body_id === 'home' )
{
$html .= '<h1>I am home!</h1>';
}
else
{
$html .= '<p>I\'m not home.</p>';
}
echo $html;
This will echo the html code depending on the $body_id variable and what it contains.
You can use a switch command like so:
switch($body)
{
case 'home': //$body == 'home' ?
echo '<h1>I am home!</h1>';
break;
case 'not_home':
default:
echo '<p>I'm not home.</p>';
break;
}
The default means that if $body does not match any case values, then that will be used, the default is optional.
Another way is as you say, if/else statements, but if within template / view pages you should try and use like so:
<?php if ($body == 'home'):?>
<h1>I am home!</h1>
<?php else:?>
<p>I'm not home!</p>
<?php endif; ?>
Assuming $bodyID is a variable:
<?php
if ($bodyID==='home') {
echo "<h1>I am home!</h1>";}
else {
echo "<p>I'm not home!</p>";}
?>
Personally I think that the best way to do that without refreshing and without having to set a variable (like $body or something like that) is to use a javascript code, this because "communications" between JS & PHP is a one-way communication.
<script language="javascript">
<!--
if( document.body.id === "home" ){
window.document.write("<h1>I am home!</h1>") ;
}
else{
window.document.write("<p>I'm not home!</p>") ;
}
-->
</script>
otherwise you can build a form and then take the body.id value using $_GET function... It always depends on what you've to do after you now body.id value.
Hope this will be usefull & clear.
you can try in the following way:
$body_id = "home";
if ($body_id == "home") {
echo "I am home!";
} else {
echo "I am not home!";
}
or
$body_id = "home";
if (strcmp($body_id, "home") !== 0) {
echo 'I am not home!';
}
else {
echo 'I am home!';
}
