I'm building a simple search engine in PHP with PDO. Everything works but fetchAll(PDO::FETCH_ASSOC) is returning me same results twice.
Here is my PHP code :
(Updated to display the id column...)
header('Content-Type: application/json');
$q = db()->prepare("SELECT id, title, description, type, mediaId FROM projects WHERE title LIKE ?");
$q->execute(array('%'.$search.'%'));
$d = $q->fetchAll(PDO::FETCH_ASSOC);
echo json_encode($d);
Here are the results I get from PDO
[
{
"id" : "1",
"title": "PhonArt",
"description": "Games",
"type": "",
"mediaId": "linkA"
},
{
"id" : "1",
"title": "PhonArt",
"description": "Games",
"type": "",
"mediaId": "linkA"
},
{
"id" : "2",
"title": "BioState",
"description": "Biology",
"type": "",
"mediaId": "linkB"
},
{
"id" : "3",
"title": "SnaPhones Inc.",
"description": "A social network",
"type": "",
"mediaId": "linkC"
},
{
"id" : "2",
"title": "BioState",
"description": "Biology",
"type": "",
"mediaId": "linkB"
},
{
"id" : "3",
"title": "SnaPhones Inc.",
"description": "A social network",
"type": "",
"mediaId": "linkC"
}
]
I've been struggling around this for a while now and can't seem to get the right algorithm.
What I want is to sort this:
$variable = '{
"0": {
"id": "0",
"code": "main_colour",
"label": "Main Colour",
"options": [{
"id": "825",
"label": "White",
"products": ["1", "2", "3"]
}, {
"id": "840",
"label": "Cream",
"products": ["3", "4", "5"]
}],
"position": "0"
},
"2": {
"id": "0",
"code": "size",
"label": "Size",
"options": [{
"id": "825",
"label": "S",
"products": ["1", "2", "3"]
}, {
"id": "840",
"label": "M",
"products": ["3", "4", "5"]
}],
"position": "0"
}
}';
And the output would be
$variable = '{
"0": {
"id": "0",
"code": "main_colour",
"label": "Main Colour",
"options": [{
"id": "840",
"label": "Cream",
"products": ["3", "4", "5"]
},{
"id": "825",
"label": "White",
"products": ["1", "2", "3"]
}],
"position": "0"
},
"2": {
"id": "0",
"code": "size",
"label": "Size",
"options": [{
"id": "840",
"label": "M",
"products": ["3", "4", "5"]
}, {
"id": "825",
"label": "S",
"products": ["1", "2", "3"]
}],
"position": "0"
}
}';
So basically it should be sorted using the label inside the "options" without affecting the other fields. I've been trying usort and tried different algorithms but to no avail.
Current code that sorts only the outside "label" and not the inner label:
function optionsSort($a, $b) {
return strcmp($a['options'][0]['label'], $b['options'][0]['options']['label']);
}
usort($variable, "optionsSort"));
Here's the code:
// your array
$variable = '{
"0": {
"id": "0",
"code": "main_colour",
"label": "Main Colour",
"options": [{
"id": "825",
"label": "White",
"products": ["1", "2", "3"]
}, {
"id": "840",
"label": "Cream",
"products": ["3", "4", "5"]
}],
"position": "0"
},
"2": {
"id": "0",
"code": "size",
"label": "Size",
"options": [{
"id": "825",
"label": "S",
"products": ["1", "2", "3"]
}, {
"id": "840",
"label": "M",
"products": ["3", "4", "5"]
}],
"position": "0"
}
}';
$a = json_decode($variable);
foreach ($a as $item) {
// sorting function
usort($item->options, function($a, $b) { return strcmp($a->label, $b->label); });
}
this is driving me nuts,
I'm trying to loop throw a specific json:
I tried using
json_encode -> throws Warning: curl_close() expects parameter 1 to be resource, null given
json_decode -> shows the same text
$json->{"SKU"} and $json->SKU shows the same text
I tried to validate the json with different websites and all say the json is correct
I want to take only this values SKU, price, specialprice (with everything inside) and quantity

Thanks a lot for any hint (I already tried almost every answer on stack)
I'm pretty sure you can do it in this way:

You can execute the code directly here.
Hope this helps.
I am trying to read posts under each category as shown below. There are multiple categories with id "4", "3", "2", "1". Only for category "1" there is a post available.
foreach ($wp_categories as $wp_category) {
$id = $wp_category->term_taxonomy_id;
//if($id == "1") {
$posts = $json_api->introspector->get_posts(array(
'cat' => $id
));
//}
$result[] = $posts;
}
return $result;
In the above code if I just uncomment the if condition, I am getting the posts in the result array. But if this is commented I am not getting the posts in result.
I am new to PHP and above condition is not making any sense. It would be of great help if someone could explain why having the if condition is making the post available in the result.
dumping $wp_categories below
{
"status": "ok",
"0": {
"term_id": "5",
"name": "Category 5",
"slug": "category5",
"term_group": "0",
"term_order": "1",
"term_taxonomy_id": "5",
"taxonomy": "category",
"description": "",
"parent": "0",
"count": "0"
},
"1": {
"term_id": "2",
"name": "Category 4",
"slug": "category4",
"term_group": "0",
"term_order": "2",
"term_taxonomy_id": "2",
"taxonomy": "category",
"description": "",
"parent": "0",
"count": "0"
},
"2": {
"term_id": "3",
"name": "Category 3",
"slug": "category3",
"term_group": "0",
"term_order": "3",
"term_taxonomy_id": "3",
"taxonomy": "category",
"description": "",
"parent": "0",
"count": "0"
},
"3": {
"term_id": "4",
"name": "abc",
"slug": "abc",
"term_group": "0",
"term_order": "4",
"term_taxonomy_id": "4",
"taxonomy": "category",
"description": "",
"parent": "0",
"count": "0"
},
"4": {
"term_id": "1",
"name": "Others",
"slug": "others",
"term_group": "0",
"term_order": "5",
"term_taxonomy_id": "1",
"taxonomy": "category",
"description": "",
"parent": "0",
"count": "1"
}
}
This is simply shows that it will be true only in case of id 1:
if($id == "1") {
I think this should be:
if(isset($id) && $id != '') {
to get the all the post.
This question already has answers here:
How can I access and process nested objects, arrays, or JSON?
(31 answers)
Closed 9 years ago.
In CodeIgniter, in PHP to create a nested-like elements for dropdown <select> I'am using this function:
function list_categories(&$result, $cats, $sub = ''){ // <- THIS
foreach($cats as $cat){
//$cat['category']->id = $sub.$cat['category']->title;
$result[$cat['category']->id] = $sub.$cat['category']->title; // <- THIS
if( sizeof($cat['children']) > 0 ){
$sub2 = str_replace('—→ ', '–', $sub);
$sub2.= '–→ ';
list_categories($result, $cat['children'], $sub2); // <- THIS
}
}
}
// Make an array available outside the function
$categoryData = array(0 => '-- '.lang('FORM_SELECT_CATTOP').' --');
// Launch the function to fill out the array with nested sets
list_categories($categoryData, $categories);
Which generates the HTML <select> list:
I want to do the same from retrieved JSON in jQuery but can't find the answer to go deeper than first level of JSON objects with this jQuery function:
$.getJSON('../raw_get_categories/'+com_id_selected+'/0', function(data){
var items = [];
$.each(data, function(key, value, sub){
items.push('<option id="'+ key[0] + '">' + value[0] + '</option>');
});
console.log(items);
});
And this is the JSON I want to manage and retrieve the same values from it like in PHP code:
{
"28": {
"category": {
"id": "28", // <<< I need to retrieve THIS

Could someone suggest me the appropriate way to achieve the same foreach statement in jQuery pls?
Juste use point to get more childs
$.getJSON('filename.php', function(data) {
$('#List li').remove();
$.each(data, function(index, item) {
$('#list').append('<li>'+item.category.id+'</li>');
});
});
You can do something like this:
$.each(data.actions, function(entryIndex, entry) {
var html = '<li class="top-level">' + this.action + '</li>';
});
