IF/ELSE to echo image in PHP
I am trying to echo a specific image based on the results of a IF/ELSE statement, however I can't quite work out the phrasing of the IF/ELSE statement. I'm a relative newbie to PHP, so I'm sure that it's just a little error in the code somewhere, but if anyone could offer any assistance, I'd be grateful!
I'm currently at the stage below:
<?php
$fresh = if ($reviews['reviews']['freshness']) = 'fresh' {
echo '<img src="assets/images/fresh.png" class="rating" title="Fresh" alt="Fresh" />';
} else {
echo '<img src="assets/images/rotten.png" class="rating" title="Rotten" alt="Rotten" />';
}
?>
<?php
foreach($reviews['reviews'] as $rv){
if ($tmp++ < 10);
echo $fresh;
echo '<li>' . $rv['quote'] . '</li>';
}
?>
Thank you!
you cant assign if statement to a value.
if ($reviews['reviews']['freshness'] == 'fresh') {
echo '<img src="assets/images/fresh.png" class="rating" title="Fresh" alt="Fresh"/>';
} else {
echo '<img src="assets/images/rotten.png" class="rating" title="Rotten" alt="Rotten" />';
}
another prettier way would be:
if ($reviews['reviews']['freshness'] == 'fresh') {
$image = "fresh";
}
else {
$image = "rotten";
}
echo '<img src="assets/images/' . $image . '.png" class="rating" title="Rotten" alt="Rotten" />';
Yup, your code is pretty wrong, but I can see what you're trying to do.
<?php
if ($reviews['reviews']['freshness'] == 'fresh') {
$image = '<img src="assets/images/fresh.png" class="rating" title="Fresh" alt="Fresh" />';
} else {
$image = '<img src="assets/images/rotten.png" class="rating" title="Rotten" alt="Rotten" />';
}
?>
Your main mistake there is the incorrect positioning of brackets, and the fact that the IF statement does NOT return a value in PHP.
That said, I'm not sure why you're doing your foreach loop underneath, so I've not touched that; perhaps you could explain further what you're trying to achieve?
这可能会帮助你朝正确的方向发展:
<?php
if ($reviews['reviews']['freshness'] == 'fresh'){
echo '<img src="assets/images/fresh.png" class="rating" title="Fresh" alt="Fresh" />';
}
else{
echo '<img src="assets/images/rotten.png" class="rating" title="Rotten" alt="Rotten" />';
}
while($reviews['reviews']){
for($i=0;i<10;i++{
echo // What do you actually want to print out?
echo '<li>'.$reviews['reviews']['quote'].'</li>';
}
}
?>
