## junior programmer – Build a product that would allow developers to learn and practice directly for the jobs they want

Hi guys, my startup is Zero to Career (www.zerotocareer.com) and we are in the process of developing our MVP.

We are developing a Direct to Career platform where people can learn and practice directly for the job they want. Basically, you can choose a role and an employer, learn what you need, and then train with identical projects using the same stack and tools. Once you are ready, you start working on a virtual product that looks like one of the employers' products, performing tasks identical to those of the role you have chosen.

For example, you could take a frontal role and use an API developed by someone else. Or you might be required to refactor or debug a code base, or add or modify a feature – all the activities carried out by developers in real life – and see their efforts lead to virtual products.

Employers are registered on the platform and can see your progress in real time (if desired) and call you for an interview based on how you get there. And all of this is free.

I only target entry level software roles to give people a fair idea of ​​how to work in a product team, how the different layers of an application interact, etc. The feedback system also helps you to improve areas where you might be weak. .

I only have a few questions to ask you and you can even answer yes / no.

Would this product be valuable enough for you to use it?
If not, is there a pain point that I am not treating?

I really appreciate you guys. It is you who would use it so it is you that I want to know. Thanks again. I hope this question will not be closed: /

## Higher revenues than product revenues

Hi guys

Someone could explain to me that on my revenue overview, I got a higher amount than in product performance.

There is a huge difference and in fact I don't know why.

I am attaching two files below to show the problem.

Thank you!!!

## wp query – Adding arguments to the WooCommerce product loop using AJAX

I'm trying to create an AJAX product filter for my WooCommerce store page. Previously, I had created the query myself and I was not using the store page. However, I want to make my code more compatible with WC.

At the moment, I can define variables from the query string to filter the WooCommerce product loop.

I do this with the following code:

``````    add_action('pre_get_posts', 'filter_pre_get_posts' );
function filter_pre_get_posts( \$wp_query ) {
if(is_shop()){
\$filter_term = \$_GET('brand');
if (isset(\$filter_term ) && !empty(\$filter_term )) {
\$wp_query->set('tax_query', array(
'relation' => 'OR',
array(
'taxonomy' => 'pa_branding',
'field' => 'slug',
'terms' => \$filter_term ,
'include_children' => true,
'operator' => 'IN'
),
array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => \$filter_term ,
'include_children' => true,
'operator' => 'IN'
),
array(
'taxonomy' => 'product_tag',
'field' => 'slug',
'terms' => \$filter_term ,
'include_children' => true,
'operator' => 'IN'
)
));
}
}
}
``````

I now want to be able to do the same by clicking on a checkbox.

On a clicked check box, Javascript adds the value of the check box in an object with arrays:

``````var object = {
'tags' : (),
'priceRange' : (),
};

\$('.checkbox-tag').change(function() {
if(\$(this).prop("checked") == true){
object.tags.push(\$(this).val());
} else if(\$(this).prop("checked") == false) {
var x = object.tags.indexOf(\$(this).val());
object.tags.splice(x,1);
}
console.log(object);
var formData = object;
aJaxFilter(formData);
});
\$('.checkbox-price').click(function() {
if(\$(this).prop("checked") == true){
var string = (\$(this).val());
object.priceRange = string.match(/d+/g);
}
console.log(object);
var formData = object;
aJaxFilter(formData);
});
``````

I then use Ajax to send this object.

``````function aJaxFilter(formData) {
\$.ajax({
url: js_variables.ajaxURL,
type:'GET',
data: {
'formData' : formData,
'action' : 'listFilteredProducts'
},
success:function(data){
console.log(data);
\$('.chd-shop-product-loop .products').html(data);
}
});
}
``````

What I'm trying to do now is to change the product loop, much like what I did with wp_query-> set () using the parameters in the first piece of coded.

I tried to follow in the Ajax function ->

``````add_action('wp_ajax_listFilteredProducts', 'listFilteredProducts');

function listFilteredProducts(\$wp_query) {
if(isset(\$_GET('formData'))) {
\$value = \$_GET('formData');
}
// If no price input, but tags have been input
if (\$value('priceRange') == 0 && \$value('tags') != 0) {
\$wp_query->set('tax_query', array(
'relation' => 'OR',
array(
'taxonomy' => 'product_tag',
'field' => 'slug',
'terms' => \$value('tags'),
),
array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => \$value('tags'),
),
array(
'taxonomy' => 'pa_branding',
'field' => 'slug',
'terms' => \$value('tags'),
),
));
//If price has been input, but no tags have been input
} else if (\$value('priceRange') != 0 && \$value('tags') == 0) {
\$wp_query->set('meta_query', array(
array(
'key' => '_price',
'value' => array(\$value("priceRange")(0), \$value("priceRange")(1)),
'compare' => 'BETWEEN',
'type' => 'NUMERIC'
)
));
//if neither price or tags input
} else if (\$value('priceRange') == 0 && \$value('tags') == 0) {
\$wp_query->set('post_type', 'product');
// if tags and price input
} else if(\$value('priceRange') && \$value('tags')) {
\$wp_query->set('tax_query', array(
'relation' => 'OR',
array(
'taxonomy' => 'product_tag',
'field' => 'slug',
'terms' => \$value('tags'),
),
array(
'taxonomy' => 'product_cat',
'field' => 'slug',
'terms' => \$value('tags'),
),
array(
'taxonomy' => 'pa_branding',
'field' => 'slug',
'terms' => \$value('tags'),
),
));
\$wp_query->set('meta_query', array(
'relation' => 'AND',
array(
'key' => '_price',
'value' => array(\$value("priceRange")(0), \$value("priceRange")(1)),
'compare' => 'BETWEEN',
'type' => 'NUMERIC'
)
));
}
wp_die();
}

## functional analysis – Numerical range of the tensor product of two matrices

Let $$T in M_n$$. Is the following true
$$bigcap limits_ {B in M_2 \ text {tr} (B) = 0} left {X in M_2: W (X) subseteq W (T) text {and} W ( B otimes X) subseteq W (B otimes T) right } subseteq bigcap limits_ {B in M_2} ​​ left {X in M_2: W (B otimes X) subseteq W (B otimes T) right }?$$ or $$W (S): = { langle Sx, x rangle: Vert x Vert = 1 }$$ is called the numeric range of $$S$$.

comments I checked the above in MATLAB using a particular choice of $$T, B$$ which turns out to be affirmative for these cases. Then I tried to prove the above in the following way:

• We know that $$W (X) subseteq W (T)$$ if a card $$varphi: text {span} {I, T, T ^ * } rightarrow text {span} {I, X, X ^ * }$$ S. T. $$varphi (aI + bT + cT ^ *) = aI + bX + cX ^ *$$ or $$a, b, c in mathbb {C}$$ is positive. So hypothetically, we have a positive card say $$psi: text {span} {I_2 otimes I, text {span} {B _ { circ}, B _ { circ} ^ * } otimes text {span} {T , T ^ * } } rightarrow M_4$$ S. T.$$psi (I_2 otimes I + B otimes T + B ^ * otimes T ^ *) = I_2 otimes I_2 + B otimes X + B ^ * otimes X ^ *$$ is positive where $$B in M_2$$ S.T $$tr (B) = 0$$ and $$B _ { circ} = begin {pmatrix} 0 & 1 \ 0 & 0 \ end {pmatrix}.$$ Now I don't know if the card $$varphi$$ can be extended positively to $$text {span} {I, B _ { circ}, B _ { circ} ^ * } otimes text {span} {I, T, T ^ * }$$ to get the required result.

It may be wrong, but I don't have a counterexample yet. Thanks in advance. Any comments are greatly appreciated.

## Manually create an order with a woocommerce product ID

I am working on code to manually create a woocommerce order from a gravity submission.

I have "custom notes" that I managed to add to the order notes BUT ideally, it would be in a metadata box under the product / item line.

Any suggestions would be appreciated (I am self-taught and not an expert).

Here is my code:

add_action (& # 39; gform_after_submission_56 & # 39 ;, & # 39; post_to_third_party & # 39 ;, 10, 2);
post_to_third_party (\$ entry, \$ form) function {
\$ global woocommerce;
// use this to find the \$ entry output
var_dump (\$ entry);

``````// Make sure to add hidden field somewhere in the form with product id and define it here, If you have some other way of defining products in the form you need to make sure product id is returned in the variable below somehow
``````

\$ user_id = rgar (\$ entry, & # 39; 97 & # 39;);
\$ note = rgar (\$ entry, & # 39; 53 & # 39;);

``````\$product_id = rgar( \$entry, '71' );
``````

\$ quantity = rgar (\$ entry, & # 39; 73 & # 39;);

``````\$address = array(

'first_name' => rgar( \$entry, '98' ),
'last_name'  => rgar( \$entry, '99' ),
'company'    => rgar( \$entry, '' ),
'email'      => rgar( \$entry, '83' ),
'phone'      => rgar( \$entry, '84' ),
'address_1'  => rgar( \$entry, '88.1' ),
'address_2'  => rgar( \$entry, '88.2' ),
'city'       => rgar( \$entry, '88.3' ),
'state'      => rgar( \$entry, '88.4' ),
'postcode'   => rgar( \$entry, '88.5' ),
'country'    => rgar( \$entry, '88.6' ),

);

\$order = wc_create_order();
``````

\$ order-> set_customer_id (\$ user_id);

``````\$order->add_product( wc_get_product(\$product_id), \$quantity, \$prices);
\$order->calculate_totals();
\$order->update_status("on hold", 'pending', TRUE);
``````

## magento 2 in the category filter does not work for all product lists?

magento 2 in the category filter does not work for all product lists ??

Problems page

## seo – How do I use the same base URL prefix for category and product pages in Woocommerce?

I looked at this article https://docs.woocommerce.com/document/removing-product-product-category-or-shop-from-the-urls/ which explains that it isn’t there not good to remove product and category databases from the URL, as this will impact performance.

1. In woocommerce, I have not defined any page for the shop URL, so my shop page is considered to be the home page

2. I have a custom domain.com/shop/ as a page, which exports my design and my products

3. In the permalink settings, I have defined the following:
• Product category base: shop
• product permalink: / shop /% product_cat% /

So, in this way, my links became:
categories: domain.com/shop/category-name
products: domain.com/shop/category-name/product name

I am satisfied with the "look" of this structured URL because it makes sense to me and to a client. the / shop / page is also searchable (as opposed to a normal prefix that does not exist) because I created it and also displays the products

However, the category pages now give a 404 error message, but the product pages work.
If someone has a good recommendation on how to fix this problem, it will not affect the performance.
I'm not entirely sure what kind of performance impact will it have if I remove the prefixes as explained in the woocommerce article I linked to.

Is there a good solution to this?

Thank you
Claudiu

## product design – Need advice

I work in the start-up start-up which has not yet launched a service and I am thinking of a career change because there is no commitment for the future role.

What is the best way to show the works what they have done? I don't want to cause any problems to expose their business model, but I am the only designer to have built their platform. And I think it is important to point out how I made the design decision and to tell what the context of the product is. What should I do?

## seo – Structured product data store, does it need a certain aspect ratio of product image?

I am building an online store for a customer and looking at the google information regarding structured "product" data.

I noticed in their article that they specified to point to a product photo (of course) but in their examples, they specified to use 16/9 4/3 or 1/1 images . Is it a rule for the product image to be used in rich extracts? I can't seem to find any information online about this.

My client has 1400px x 1600px product images so they are not in the format specified.

On top of that, when I test the page code with Google's Rich Snippet test tool, everything looks good, there are no errors and it says that my page is correct. But when I press the preview button, it doesn't seem to work. It only displays the following error:
