Support for IF ELSE about docxtemplater

[edi9999]

If you want to test if the array is empty, you can use the inversed loop tags:

{#users}
User: {name}
{/users}

{^users}
No Users ...
{/users}

Will output "No Users ..." if the users array is empty

Hey,

the way to do if else is to use table templating:

 {#ifFormatting}
     //table 1
 {/ifFormatting}

 {#elseFormatting}
    // table 2
 {/elseFormatting}

with the following data:

 {
     "ifFormatting":[],  //This will not show what's inside ifFormatting
     "elseFormatting":[{tableData:""}] //This will show what's inside elseFormatting once
 }

I will maybe add the possibility to use "ifFormating":true instead, without changing the working scope, so that would be the same as what Mustache does

[edi9999]

Actually I have added this functionality:

If the docx template is

{#ifFormatting}
{/ifFormatting}

and ifFormatting===true, then what is inside the scope will be shown and the scope won't be changed.

how can i use array.length in if condition.
{#array.length}
{some_actions_with_array}
{/array.length}
seems to be not working

problem when i use {-w:p smth}{smth} when the array is empty

hi

can you also do something like this

{#myVar == 'value1'}
// pring if myVar is value1
{/}

Thanks

Yes, search in the docs for angular parser

[adadi-arc]

i need if else condition like this

{#dogName} German {/} else not found

[edi9999]

Hello @adadi-arc ,

there are two possibilities :

1. Use {#dogName} and then {^dogName}, like this :

{#dogName}German{/}{^dogName}not found{/}

or you can also use the angular expression parser and a ternary :

2. {dogName ? " German " : "not found"}

This second solution needs the following code :

const expressionParser = require("docxtemplater/expressions.js");
const doc = new Docxtemplater(zip, {
    paragraphLoop: true,
    linebreaks: true,
  parser: expressionParser,
});
doc.render({
    first_name: "John",
    last_name: "Doe",
    phone: "0652455478",
    description: "New Website",
});

I have a question. Suppose there's a paragraph on a new page displayed depending on a condition. I want it to show the text when the condition is true; otherwise, it should generate a blank page. However, I don't want it to generate a blank page if the condition is false

[edi9999]

I think this could be solved by using the following trick :

https://docxtemplater.com/docs/faq/#adding-page-break-from-a-tag

[adadi-arc]

I'm encountering this error when using page break.
the tag \ pagebreak\ is not inside a paragraph, putting raw tags inside an inline loop is disallowed. ,

Can we connect on WhatsApp to discuss it?

Please make sure first to upgrade to the latest docxtemplater version, 3.45.0

If you write your document like this :

{#cond}
{@pageBreak}
{text}
{/}

And use the following in your code :

const doc = new Docxtemplater(zip, {
    paragraphLoop: true,
    linebreaks: true,
});
doc.render({
    cond: true,
    pageBreak: '<w:p><w:r><w:br w:type="page"/></w:r></w:p>',
    text: "Hello world",
});

(The paragraphLoop: true option is important, it will automatically remove empty paragraphs inside those types of loops).

It is not possible to add a {@Pagebreak} inside a given paragraph, for example :

Foo{@pageBreak}

is invalid, as well as :

{#cond}{@pageBreak}{/}

You have to write :

{#cond}
{@pageBreak}
{/}

If that still doesn't work and you have applied everything above, please send your template.
