I'm getting this error:
" Warning: Invalid argument supplied for foreach() in /home/content/73/9889573/html/wp-content/themes/yoo_spark_wp/warp/systems/wordpress.3.0/helpers/system.php on line 310 "
Can someone tell me how do i fix it
wp_get_sidebars_widgets() returns a 1-dimensional array.
Reference: http://codex.wordpress.org/Function_Reference/wp_get_sidebars_widgets
$ids is not an array. You cannot traverse it in a foreach loop.
Try this:
$widgets = array();
foreach (wp_get_sidebars_widgets() as $pos => $id) {
$widgets[$pos] = $this->getWidget($id);
}

What causes this warning?
You should check that what you are passing to foreach is an array by using the is_array function
If you are not sure it's going to be an array you can always check using the following PHP example code:
if (is_array($variable)) {
foreach ($variable as $item) {
//do something
}
}
This means that you are doing a foreach on something that is not an array.
Check out all your foreach statements, and look if the thing before the as, to make sure it is actually an array. Use var_dump to dump it.
Then fix the one where it isn't an array.
How to reproduce this error:
<?php
$skipper = "abcd";
foreach ($skipper as $item){ //the warning happens on this line.
print "ok";
}
?>
Make sure $skipper is an array.
Because, on whatever line the error is occurring at (you didn't tell us which that is), you're passing something to foreach that is not an array.
Look at what you're passing into foreach, determine what it is (with var_export), find out why it's not an array... and fix it.
Basic, basic debugging.
Try this.
if(is_array($value) || is_object($value)){
foreach($value as $item){
//somecode
}
}
$data = file_get_contents($file);
$fexplode = explode(PHP_EOL, $data);
foreach ($fexplode as $uline) {
foreach (unserialize($uline) as $item => $value){
echo $item . " : ";
echo $value;
}
}
Getting a "Warning: Invalid argument supplied for foreach() " warning on my page when running this code
use below way
$data = file_get_contents($file);
$fexplode = (!empty($data)?explode(PHP_EOL, $data):array()); // use !empty otherwise make empty array
foreach ($fexplode as $uline) {
foreach (unserialize($uline) as $item => $value){
echo $item . " : ";
echo $value;
}
}
I have the following error in the code below.
Warning: Invalid argument supplied for foreach() in

I checked on another server and does not appear this error (php5.4) but my server with php5.3, php5.5 appear. What's missing?
if (isset($_GET['jsonstring'])) {
if($this->validate()){
$jsonstring = $_GET['jsonstring'];
$jsonDecoded = json_decode(html_entity_decode($jsonstring));
function parseJsonArray($jsonArray, $parentID = 0) {
$return = array();
foreach ($jsonArray as $subArray) {
$returnSubSubArray = array();
if (isset($subArray->children)) {
$returnSubSubArray = parseJsonArray($subArray->children, $subArray->id);
}
$return[] = array('id' => $subArray->id, 'parentID' => $parentID);
$return = array_merge($return, $returnSubSubArray);
}
return $return;
}
$readbleArray = parseJsonArray($jsonDecoded);
foreach ($readbleArray as $key => $value) {
if (is_array($value)) {
$this->model_menu_megamenu->save_rang($value['parentID'], $value['id'], $key, $data['active_module_id']);
}
}
die("The list was updated ".date("y-m-d H:i:s")."!");
} else {
die($this->language->get('error_permission'));
}
}
Change
$jsonDecoded = json_decode(html_entity_decode($jsonstring));
to
$jsonDecoded = json_decode(html_entity_decode($jsonstring),true);
and $jsonDecoded will be an array
i think i some cases we have to use implode and explode functions when we work with json data in php, try this after decoding your json data to convert an string to an array.
In following code i has error in view, how can fix it?
My data in table is as:
CI_Controller:
$update = array('15'); // this is a example from my $_POST that are array.
if (is_array($update) && count($update) > 0) {
foreach($update as $val){
$data['query_hi'] = $this->db->get_where('hotel_image', array('relation' => $val))->row();
}
$this -> load -> view('admin/residence_update', $data);
}
View:
foreach($query_hi->images as $val){
echo $val;
}
Error:
A PHP Error was encountered
Severity: Warning
Message: Invalid argument supplied for foreach()
Filename: core/Loader.php(679) : eval()'d code
Line Number: 279
The problem is that it returns only one result for your query... and the array is overridden at each cycle. Try this:
$update = array('15'); // this is a example from my $_POST that are array.
if (is_array($update) && count($update) > 0) {
$data= array();
foreach($update as $val){
$tmp= $this->db->get_where('hotel_image', array('relation' => $val));
foreach($tmp->result() as $row){
$data['query_hi'][] = $row;
}
}
$this -> load -> view('admin/residence_update', $data);
}
Maybe you should try:
for($i=0;$i<count($query_hi);$i++)
{
echo $query_hi[$i]->images;
}
