I'm trying to take the values of an array and display it as a list. I've used a foreach to do this before but for some reason I can't figure out why it's not working this time around. In the code below, $output is the contents of an entire page generated through AJAX and is later echo'd out on the bottom of the script. Everything seems to be working except this one small section. I managed to get this exact same information to display on a separate static page (without the $output) so I'm not sure why it's not working here.
if(!empty($record['utilities'])) {
$output .= "<ul>";
foreach ($record['utilities'] as $eachUtility):
// $output .= "<li>" echo $eachUtility; "</li>";
$output .= "<li>" . $eachUtility . "</li>";
endforeach;
$output .= "</ul>";
// $output .= $record['utilities']; This works
}
Here's a working example of the same code that was hard coded on a separate page:
<?php if(!empty($record['utilities'])) { ?>
<ul>
<?php foreach ($record['utilities'] as $eachUtility): ?>
<?php echo ('<li>' . $eachUtility . '</li>'); ?>
<?php endforeach ?>
</ul>
<?php } ?>
Try this:
$output = "<ul>";
foreach ($record['utilities'] as $eachUtility) {
$output .= "<li>" . $eachUtility . "</li>";
}
$output .= "</ul>";

I need a little help on getting a rule in to output something else if a certain variable is called.
To break it down I have the following listed:
private $zebra_moto_symbol = array
( "ES400", "MC9500", "MC9200", "MC9190", "MC9094", "MC9090", "MC9097", "MC9060",;
and using this code it pulls the models into the page in a list:
public function manufacturer_models_list() {
$manu_name = $this->manufacturer_name;
$output = "<ul>";
sort($this->$manu_name);
foreach($this->$manu_name as $model) {
$output .= "<li>" . "" . $model . "</li>";
}
$output .= "</ul>";
$output .= "<p class=\"clear\"></p>";
$output .= "Arrange A Repair";
return $output;
}
On all but two of these, I need it display the repair.php link, however on two these need to be different. What would I need to input to make this happen?
Thanks in advance (sorry, this one stumped me).
:)
You can use a switch statement for this.
<?
public function manufacturer_models_list() {
$manu_name = $this->manufacturer_name;
$output = "<ul>";
sort($this->$manu_name);
foreach ($this->$manu_name as $model) {
switch($model) {
//Output NOT repair.php on this list of strings
case "ES400":
case "MC9500":
$output .= "<li>DIFFERENT OUTPUT</a></li>";
break;
//default is the action that happens if none of the previous conditions are met
default:
$output .= "<li>" . "" . $model . "</li>";
break;
}
}
$output .= "</ul>";
$output .= "<p class=\"clear\"></p>";
$output .= "Arrange A Repair";
return $output;
}
?>

If I understood correctly, what you want is to have a different output on certain values.
I would think about have another array to hold the values that you want a different output and you can do something like this:
$different_output_array = ['ES400', 'MC9500']; # you can add new elements any time
and just modify your function to something like this:
public function manufacturer_models_list() {
$manu_name = $this->manufacturer_name;
$output = "<ul>";
sort($this->$manu_name);
foreach($this->$manu_name as $model) {
if(in_array($model,$different_output_array))
{
$output .= "<li>" . "" . $model . "</li>";
}
else
{
$output .= "<li>" . "" . $model . "</li>";
}
}
$output .= "</ul>";
$output .= "<p class=\"clear\"></p>";
$output .= "Arrange A Repair";
return $output;
}
Hope this can help.
I'm pretty new to php and I can't figure out why 'testimonial_text' is not being wrapped within the 'testimonial-text' class. For some reason, it's outputting 3 elements and one of them is "testimonial text" but it's not within the "testimonial-text". "testimonial_author" is being correctly wrapped in "testimonial-author". Any ideas?
<?php
$rows = get_field('testimonials');
if($rows) {
foreach($rows as $row) {
$output = "<div class = 'testimonial-container'>";
$output .= "<p class = 'testimonial-text'>".$row['testimonial_text'] . "</p>";
$output .= "<p class = 'testimonial-author'>".$row['testimonial_author'] . "</p>";
$output .= "</div>";
echo $output;
}
}
?>
Following the image showing the contents of $rows in the comments it looks like the data you are returning has extra code and/or quotes in it. So I would recommend doing something like..
if($rows) {
$output = '';
foreach($rows as $row) {
$output .= "<div class = 'testimonial-container'>";
$output .= "<p class = 'testimonial-text'>" . strip_tags ($row['testimonial_text']) . "</p>";
$output .= "<p class = 'testimonial-author'>" . strip_tags ($row['testimonial_author']) . "</p>";
$output .= "</div>";
}
echo $output;
}
To remove any stray code that is getting output.
Worth noting #Naumov said to use strip_tags as well :)
Ive been trying make this display as html list items it just a string that i explode then loop over each item i cant get it to out put correctly. Could some one please show me where im going wrong or suggest an new approch.
this is what ive tried
$path = "1/2/3/4";
$expath = explode("/",$path);
$ret = '';
echo '<ul>';
foreach ($expath as $pitem) {
echo '<li><a href='.$ret .= $pitem. "/".'>'.$pitem.'</a></li>';
}
echo '</ul>';
.
Desired out put on hrefs
1
1/2
1/2/3
1/2/3/4
Desired visual out LIs
1
2
3
4
Output i get be warned
1
12/>212/>23/>312/>23/>34/>4
$path = "1/2/3/4";
$expath = explode("/", $path);
echo '<ul>';
foreach ($expath as $i => $pitem) {
$slice = array_slice($expath, 0, $i + 1);
$path = implode('/', $slice);
echo '<li>' . $pitem . '</li>';
}
echo '</ul>';
$list = explode("/", "1/2/3/4");
This will create an array $list as:
echo $list[0]; // 1
echo $list[1]; // 2
echo $list[2]; // 3
echo $list[3]; // 4
This line is the problem: echo '<li><a href='.$ret .= $pitem. "/".'>'.$pitem.'</a></li>';
Should be formatted like:
echo "<li><a href='{$ret}={$pitem}/'>{$pitem}</a></li>";
or echo '<li>'.$pitem.'</li>';
Its because your $ret. Place that inside the loop. In your code you concatenate $pitem with $ret all older $ret values also get concat.
Try
<?php
$path = "1/2/3/4";
$expath = explode("/",$path);
echo '<ul>';
foreach ($expath as $pitem) {
$ret = '';
echo '<li><a href='.$ret .= $pitem. "/".'>'.$pitem.'</a></li>';
}
echo '</ul>';
If you want = sign tobe there in the url then just change echo by following
echo "<li><a href='$ret=$pitem/'>$pitem</a></li>";
PHP echo with double quotes will print variable value.
$menu = array(
0 =>'top',
1 =>'photography',
2 =>'about'
);
<?php
function main_menu ($menu) {
$return = '<div class="menu_entry">' . PHP_EOL .'';
foreach( $menu as $key => $value)
{
$return .= '<a class="menu" href="index.php#' . $menu[$key] . '">' . $menu[$key] . '</a>' . PHP_EOL .'';
}
$return .= '</div>';
return $return;
}
?>
<?php echo main_menu($menu[1]); ?>
What i basically want to do is to pass a specific array value when i'm echoing out the menu.
I'm building a single page website with anchors and i want to pass value's so i can echo out the "top"-link.
I'm stuck at the point on how to pass the $key value trough the function.
**edit: I'm trying to print specific links. I want a function that is able to print out an link but i want to specify the link to print via the function argument.
for example:
<?php echo main_menu($key = '0'); ?>
result:
prints url: top
<?php echo main_menu($key = '2'); ?>
result:
prints url: photography
**
(A lack of jargon makes it a bit harder to explain and even harder to google.
I got my books in front of me but this is taking a lot more time than it should.)
You either need to pass the entire array and loop, or pass a single array item and not loop:
Single Item:
function main_menu ($menu) {
$return = '<div class="menu_entry">' . PHP_EOL .'';
$return .= '<a class="menu" href="index.php#' . $menu . '">' . $menu . '</a>' . PHP_EOL .'';
$return .= '</div>';
return $return;
}
echo main_menu($menu[1]);
Entire Array:
function main_menu ($menu) {
$return = '<div class="menu_entry">' . PHP_EOL .'';
foreach($menu as $value) {
$return .= '<a class="menu" href="index.php#' . $value . '">' . $value . '</a>' . PHP_EOL .'';
}
$return .= '</div>';
return $return;
}
echo main_menu($menu);
You don't need $menu[$key] just use the $value.
Should you not just be using $value inside your loop? And passing the entire array rather than one item of the $menu array?
$menu = array(
0 =>'top',
1 =>'photography',
2 =>'about'
);
<?php
function main_menu ($menu) {
$return = '<div class="menu_entry">' . PHP_EOL .'';
foreach( $menu as $key => $value)
{
$return .= '<a class="menu" href="index.php#' . $value . '">' . $value . '</a>' . PHP_EOL .'';
}
$return .= '</div>';
return $return;
}
?>
<?php echo main_menu($menu); ?>
Try:
echo main_menu($menu); // You will get your links printed
Instead of
echo main_menu($menu[1]); // In this case error is occured like : **Invalid argument supplied for foreach**
NOTE: You can use $value instead of $menu[$key]
I have a field in my database with the text value:
"these, are, some, keywords" (minus the inverted commas)
Now, I wonder if I can generate an unordered list from this so ultimately my HTML reads:
<ul>
<li>these</li>
<li>are</li>
<li>some</li>
<li>keywords</li>
</ul>
Is this possible with PHP and if so is anyone able to help me out with this?
Many thanks for any pointers.
You can accomplish this with something like the following:
<?php
$yourList = "these, are, some, keywords";
$words = explode(',', $yourList);
if(!empty($words)){
echo '<ul>';
foreach($words as $word){
echo '<li>'.htmlspecialchars($word).'</li>';
}
echo '</ul>';
}
?>
As mentioned by elcodedocle, you may want to use str_getcsv() instead of explode if more appropriate.
Have a look at str_getcsv() and explode()
Example:
<?php
$mystring = "these, are,some , keywords";
$myvalues = str_getcsv($mystring);
$myoutput = "<ul>";
foreach ($myvalues as $value){
$myoutput .= "<li>".trim($value)."</li>\n";
}
$myoutput .= "</ul>";
echo $myoutput;
?>
You need to explode you string for ', '
print <ul>
for each element in the array you received you print '<li>' . $value . '</li>'
print </ul>
You can try:
$arr = explode(",","these, are, some, keywords");
$res = "<ul>";
foreach ($arr as $val){
$res .= "<li>" . $val . "</li>";
}
$res .= "</ul>";
echo $res;
