Condition to display a slider on a certain Web page?

Hey, everybody, there's a MetaSlider slider, the installation is that the following code should be added on the page, this code is in the header.php:
```
<?php echo do_shortcode('[metaslider id="4"]'); ?>
```
How can you spell out the condition that this code only operate on a certain page?

Use the conditional theater.
For example, if you need to take the slider off only on the main:
```
<?php
if ( is_front_page() ) {
  echo do_shortcode('[metaslider id="4"]');
}
?>
```
Read the other conditional theories:

Right. Because andThe shifts are different from behavior, but by name. It's a somewhat uncommon concept, but Name Class of exception means more than the name of any other language operator. By name, we're intercepting exceptions. I mean, if we need different processors for different exceptions, then we'll be different by name. This is, in fact, the very reason why it is recommended that each person should make an exception.To replace catch (Exception $e) You could write. catch (fooException $e) and catch only one very specific mistake.

In order for certain websites of the list to give different kinds, it is necessary to establish a self-marking for each type of web, how they will look and redesign two methods in the adapter:getItemViewType(position) - contains a condition on which it can be determined that the website of which form can be taken into the current position. The identifier of this site returns. getViewTypeCount() - returns the number of webs of different kinds.Let's make a simple list of two types of web: item_normal.xml - general appearance and item_big.xml - the type with the enlarged print (the type of print is marked directly). I don't think I'm going to make the markings. They're gonna have to do what they look like.Castom Adapter (Simple example based on ArrayAdapter - only important to understand the part:public class CustomAdapter extends ArrayAdapter { private LayoutInflater mInflater; private static final int TYPE_1 = 0; // идентификатор айтема первого типа private static final int TYPE_2 = 1; // идентификатор айтема второго типа private ArrayList mItems; public CustomAdapter(Context context, ArrayList items) { super(context, items); mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); mItems = items; } public View getView(int position, View convertView, ViewGroup parent) { // получаем идентификатор вида айтема в текущей позиции int type = getItemViewType(position); View v = convertView; //инфлейтим разметку айтема для текущей позиции switch (type) { case TYPE_1: v = mInflater.inflate(R.layout.item_normal, null); break; case TYPE_2: v = mInflater.inflate(R.layout.item_big, null); break; default: } // Если айтемы разных видов содержат разные данные для отображения // то разделяем биндинг: // // switch (type) // { // case TYPE_1: // биндинг данных в айтем первого вида. // // break; // case TYPE_2: // биндинг данных в айтем второго вида. // // break; // } // // Так как в вашем случае данные в айтемах не меняются, то для обоих // биндинг одинаковый и его не нужно разделять. String text = mItems.get(position); // извлекаем данные TextView tv = (TextView) v.findViewById(R.id.text); tv.setText(text); // размещаем в айтем return v; } @Override public int getItemViewType(int position) { // Здесь нужно определить вторую видимую позицию // и вернуть идентификатор айтема второго типа // иначе - айтема первого типа // Надо подумать. return (twoPosition) ? TYPE_2 : TYPE_1; } @Override public int getViewTypeCount() { return 2; // два различных вида айтемов } } Since, in your case, the appearance of different webs is not different than the colour and size of the prints, all of these differences you ask directly - the data is not required separately.In more complex cases, you can use any independent data for different types of websites that can contain completely different markings and separate their filling through. switch - case in a coded block.In real adaptation, better use canders and other optimizations

To send the form, at least you need to create the form. And if you don't understand anything, try to look at it. http://htmlbook.ru/html/form ♪ There's a description of the current form and his attributes, exactly what you need to know for your assignment. <form method="POST"> <p><input type="checkbox"> <input type="text"></p> <p><input type="submit"></p> </form>
How do you get access to class protected properties?

Got a class. protected properties that need access. At the same time, we may not be able to change the class code or to create and use an heir class that has access to it. protected Let's go. class Car { protected $vin = "Z8NAJL10060639823"; protected $brand = "Жигули"; } Obviously, all other options (except code and inheritance changes) are "cods."These are some of them:You can lead the object to an associated mass and gain access to the field. The key will have a prefix. \0*\0$cArray = (array)$car; $vin = $cArray["\0*\0vin"]; You can use an anonymous function by transferring your object to it as a context for access and substitution. this (for px 7)$getProperties = function($props){ $result = []; foreach($props as $p){ $result[$p] = $this->$p; } return $result; }; $props = $getProperties->call($car, ['vin']); $vin = $props['vin']; You can use reflexes.$r = new ReflectionClass($car); $prop = $r->getProperty('vin'); $prop->setAccessible(true); $vin = $prop->getValue($car); As has been written in the commentaries, where in the subsoils of the hierarchy of your model ' s inheritance, there are methods of access to secure class fields. Since we don't see the code of these class predators how they're not supposed to work specifically (but don't go to the gallows, it's all based on magic techniques). So you and I have learned that in the template, access to the variable is as follows: {{ car.Vin }}♪Since it's just access $car->Vin Gives us an empty result in the implementation of the code, and we should turn to https://twig.symfony.com/doc/2.x/templates.html And see how he interprets this syntaxy.So...For convenience's sake foo.bar does the following things on the PHP layer:check if foo is an array and bar a valid element; if not, and if foo is an object, check that bar is a valid property;if not, and if foo is an object, check that bar is a valid method (even if bar is the constructor - use __construct() instead);if not, and if foo is an object, check that getBar is a valid method;if not, and if foo is an object, check that isBar is a valid method;if not, and if foo is an object, check that hasBar is a valid method;if not, return a null value.There's a conclusion. It's the path itself. So his rules work. Because the variable is not an object, it's a characteristic. Vin We're out of range, and then the tide checks the method. $car->getVin()♪ Other checks isBar/hasBarNot very logical. So, $car->getVin() Help you.

If you only need to "hide" the content of the site before load be fired, you can use a class with this property that is inserting directly into the DOM, it is easier to handle:.hide { display: none } The content to be "hidden" while the page is loaded may initially have this class. Just then remove it when the load is fired.ps: I put an image for the 'load' to take the first load off.var loading = document.querySelector('div'), content = document.querySelector('main'); window.onload = function() { loading.classList.add('hide'); // esconde o 'carregando'. content.classList.remove('hide'); // mostra o conteúdo do site. };.hide, img { display: none }<div> <p>carregando...</p> </div> <main class='hide'> <img src='http://i.stack.imgur.com/uoKIw.jpg' /> conteúdo do site. </main>In the above example I used https://developer.mozilla.org/en-US/docs/Web/API/Element/classList but I already say that not all browsers have this resource implemented. Internet Explorer < 10 and Opera Mini 5 do not support classList - http://caniuse.com/#feat=classlist . Anyway https://stackoverflow.com/q/8098406/4056678 (en) There are possible solutions you can use.If you want to display a progress bar as the site is loaded (showing the percentage), I suggest using the http://github.hubspot.com/pace/docs/welcome/ for this.

With him https://api.jquery.com/class-selector/ , like the example below since I see that you are using JQuery in this case even if there are no group1 and group2 classes, but allow me to group and identify the checkboxes that have been checked with input:checkbox:checked.group1, without the need for a id for each one as in the example I show below, where I return an arrangement of the values of the checkboxes that have been checked<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>Ejemplo de selector checkboxes</title> <script src="https://code.jquery.com/jquery-1.9.1.min.js"></script> <script> $( document ).ready(function() { var values = $('input:checkbox:checked.group1').map(function () { return this.value; }).get(); console.log( "valores:" +values); }); </script> </head> <body> <input type="checkbox" class="group1" value="18" checked="checked" />18 group1 seleccionado<br> <input type="checkbox" class="group1" value="20" />20 group1<br> <input type="checkbox" class="group1" value="15" />15 group1<br> <input type="checkbox" class="group2" value="14" />14 group1<br> <input type="checkbox" class="group1" value="55" checked="checked" />55 group1 seleccionado<br> <input type="checkbox" class="group1" value="10" checked="checked" />10 group1 seleccionado<br> <input type="checkbox" class="group2" value="77" checked="checked" />77 <b>group2</b> seleccionado<br> <input type="checkbox" class="group1" value="11" />11 group1<br> </body> </html>

Correct me if I'm wrong, when a user requests a page to your system, a connection to the database is opened, queries are made as required, the page is displayed and the connection is closed. This operation takes two seconds. The user may be reading your page, let's say 10 minutes.If your database accepts 3 simultaneous connections, you can serve 3 connections every 2 seconds or 90 connections per minute. But even though 90 users are reading your page at the same time are not simultaneous connections, because the page in question It's already on the client.. If at the same time 5 clients arrived to request the page, and your database server accepts 3 simultaneous connections, two of those customers would expect 2 seconds to view your page. If you increase the MySQL limit to 5, then you could serve 150 pages every minute.Obviously, the more open connections you allow, the more resources you consume your system.The solution is to use temporary memories, Cachethe queries of your database and the pages generated by PHP. This cache, let's say it reduces response time to 1/2 seconds.We now move to your http server. If your server accepts 50 customers simultaneously, serving in 1/2 the cash pages, it can serve 100 simultaneous pages per second. But it's the same thing, open a connection, serve the page and close... There are no simultaneous users.This changes if you make use of websockets, but do not indicate it in your question.ResponseApache has a program called http://httpd.apache.org/docs/2.4/programs/ab.html which serves to test effort or benchmarking. Shows the number of requests per second can serve your Apache server, although I think it works for any server, because it tests under the protocol http.It's used like this:ab -n 200 -c 20 http://example.com With this you generate 100 applications in 20 threads, to verify the concurrence. On this page http://www.genbetadev.com/herramientas/apachebench-una-sencilla-herramienta-para-testear-servidores-web You can see an example.RecommendationsUnless you know for sure that your system has very high memory requirements, you should consider optimizing your code, using cache and optimizing your servers before to think about climbing your servers. A poorly programmed and/or poorly optimized system will have poor performance on a server with 1 GB or 224 Gb.
