link<\/a>.<\/p>\nMagento Follows MVC design pattern and I found that people are generally confused about layout and view system.
\nand block is a part of the View system. In magento View is separated into two parts, One is Block and another is Template.<\/p>\n
What is Block ?
\nBlock is a simple Object tied to Template file.<\/p>\n
What is Template ?
\nTemplate is a Raw phtml file (having the extention .phtml) contain php and html code. In phtml(template) file $this keyword keeps the reference of the template’s Block Object.<\/p>\n
We can perform block nesting as well. Block into Block.
\nBasically block inside block inside block is how Magento html layout is create for page.
\nFor performing Nesting we use a method getChildHtml method.<\/p>\n
getChildHtml help us to call any block in any place in particular page scope.
\nExample :<\/p>\n
Call specific block $this->getChildHtml(“head”);<\/p>\n
All child Blocks $this->getChildHtml();<\/p>\n
There are lots of terms that you should know, like layout packaging, references , handles etc,<\/p>\n
but I can not cover all in one \u00a0as I need to explain a \u00a0thing that you may need when you are creating any module \u00a0and situation came and you want to remove the block from the layout and add new block in layout.<\/p>\n
To add\/remove block in layout we need to get the reference of the layout Object. We use getLayout() method to get it’s reference.<\/p>\n
There are generally two ways to remove the block from the layout :
\n1. XML
\n2. PHP Code.<\/p>\n
First let me cover the XML part .
\nRemove \/ add Block :<\/p>\n
<?xml version=\"1.0\"?>\n<page xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\" layout=\"2columns-right\" xsi:noNamespaceSchemaLocation=\"urn:magento:framework:View\/Layout\/etc\/page_configuration.xsd\">\n <body>\n <referenceBlock name=\"head\" remove=\"true\" \/> <!--remove block -->\n <referenceBlock name=\"content\"> <!--add block -->\n <block \n class=\"<CustomVendor\\CustomModule\\Block\\CustomBlock>\"\n name=\"<myblock-name>\"\n template=\"<CustomVendor_CustomModule::test.phtml>\"\/>\n <\/referenceBlock>\n <\/body>\n<\/page><\/pre>\nAdd\/Remove Block \u00a0(PHP):<\/p>\n
$layout = $this->getLayout();\n\n$block = $layout->getBlock('content');\n \nif ($block) {\n \/\/ you can use any condition here.\n \/\/ remove block\n $block->unsetChild(\"< child block name >\");\n \/\/Or\n $layout->unsetElement('< child block name >');\n}\n\n\/\/ yo can get parent block as well from this layout.\n$parentBlockName = $layout->getParentName('<child block name>')\n$parentBlock = $layout->getBlock($parentBlockName);\n\n\/\/ create new block \n$layout->createBlock(\"<Magento\\<Theme>\\Block\\Test>\");\n<\/pre>\nNote :<\/strong> you can write the above code in block as well as in Template , it works in both places.<\/p>\nNote<\/strong> : Best Practice, we should use this code in Block’s prepareLayout() function.<\/p>\nSituation<\/strong> : When to use in Template file
\nExample : parent block has used the function getChildHtml() at the bottom and you want your block to be tied in between(middle of the page\/block).<\/p>\nScenario<\/strong> : if you will add the line after overriding the template in between the Template, so the same block will come twice so you have to remove the bottom occurrence of the block.<\/p>\nFew more function in view object :
\n1. setTemplate($template)
\n2. toHtml()
\n3. getNameInLayout()
\nThis code will help you to come out of this situation.<\/p>\n","protected":false},"excerpt":{"rendered":"
