XtGem get-variablesThese can be used on ANY XtGem site WITHOUTupgradingThis is a very complex subject so I will only cover the basics hereXtGem "get" variables can be used to replace any text or code in your site with a value that has been declared in a link or formIn your code or text a variable looks like this{_$variable_name|default_value}Original XtBoard post
a simple form to display you#form" method="get">
Enter your name

Enter your age

your name is currently unknown your age is also unknown
<form id="myform" action=" http://MY_SITE.COM#myform" ; method="get">Enter your name<br /><input type="text" name="myname" value="{_$myname|}" /><br />Enter your age<br /><input type="text" name="myage" value="{_$myage|}" /><br /><input type="submit" value="GO" /></form><br />your name is {_$myname|currently unknown } your age is {_$myage|alsounknown}The Form<form id="myform" action=" http://MY_SITE.COM#myform" ; method="get">This sets up the form and tells it where to go. (in this case back to itself)
You can also use method="post" so that thevariables will not appear in the url box<input type="text" name="myname" value="{_$myname|}" />
<input type="text" name="myage" value="{_$myage|}" />input the values for name and age
The xt variables restores the last value of name and age after the form has been submitted<input type="submit" value="GO" /></form>Submit the form and close itThe output of the formyour name iscurrently unknown
your age is also unknown
your name is {_$myname|currently unknown }
your age is {_$myage|also unknown}The Xt variables alter the text that is output
Setting the values with a linkYou can set the values in the query string of a link
my name is Ringo Starr I am 56
You start the query string with a ? and use & to separate variables
<a href=" http://MY_SITE.COM?myname=Ring o Starr&myage=56" >my name is Ringo Starr I am 56</a>This link reloads the current page with the values for name and age set
Passing values to another pageTo pass the currently set variables to another page on your site you must set the current values in the link to the new page
a new page<a href="anotherpage?myname={_$myname|}&myage={_$myage|}">A new page</a>NOTE: the <xt:url /> and <xt:referer />
hidden Xt functions
Will pass on any variables set in the url of a link or in forms using method="get"AUTOMATICALLYUsing in XT functions and widgets

This chatt box has it's custom key set by myname myage from the form above or below

Hiding thingsYou can use variables to hide or reveal parts of a page. there are 2 ways to do this
Hiding in commentsHide and show using html comments. Anything between  is ignored by the browser. This places comments at the beginning and end of a section of code
This is what the browser sees<span >This will show on page load</span>This is the actual code<{_$hid|!--}span>Hiding in comments</span{_$hid|--}> <{_$hid2|}span>This will show on page load</span{_$hid2|}>Show itnow
The code for the links
<{_$hid2|}a href=" http://MY_SITE.COM?hid=& amp;hid2=%21--">Show it now</a{_$hid2|}><{_$hid|!--}a href=" http://MY_SITE.COM?hid2="& gt;hide itnow</a{_$hid|--}>What the browser sees
<a href="http://tutorial.graham.yn.lt/Getvariables?hid=& amp;hid2=!--">Show it now</a>This will show on page load
