Implement the dedecms gallery Click image flip Function

1. To achieve this function, we first need to obtain the current page number and total page number of the image page.
Edit the include/inc_archives_view.php file.
(1) locate function parsedmfields and change it:
Function parsedmfields ($ pageno, $ ismake = 1)
{
$ This-> nowpage = $ pageno;
// Obtain the number of the current page
$ This-> fields ['cpagenum'] = $ this-> nowpage;
If ($ this-> splitpagefield! = ""&&
Isset ($ this-> fields [$ this-> splitpagefield])
{
$ This-> fields [$ this-> splitpagefield] = $ this-> splitfields [$ pageno-1];
}
Note that the following is added: Code Used to obtain the current page number:
$ This-> fields ['cpagenum'] = $ this-> nowpage;
(2) locate the function _ construct constructor and change it:
<? PHP
......
$ This-> totalpage = count ($ this-> splitfields );
}
// Obtain the total number of current pages
$ This-> fields ['totalpage'] = $ this-> totalpage;
$ This-> loadtemplet ();
$ This-> parsetempletsfirst ();
}
Note that the following code is added to obtain the total page number:
$ This-> fields ['totalpage'] = $ this-> totalpage;
2. Use Js in the template to analyze static and dynamic pages and flip pages down
Edit article_image.htm or the final template displayed in your gallery and add the following JS Code:
<Script language = "JavaScript">
VaR npage = {Dede: field name = 'cpagenum '/};
VaR totalpage = {Dede: field name = 'totalpage '/};
VaR filename = "";
VaR curl = location. href;

Function gonextpic (){
Str1 =/\. html/ig;
Str2 =/_/ig;
R = curl. Search (str1 );
R1 = curl. Search (str2 );
If (r> 0 ){
If (npage = 1) filename = curl. substr (0, R );
Else filename = curl. substr (0, R1 );

If (npage = totalpage) {location. href = filename + ". html ";}< br> else {
location. href = filename + "_" + (npage + 1) + ". html ";
}< BR >}else {
If (npage = totalpage) {location. href = "view. PHP? Aid = {Dede: field name = 'id'/} ";}< br> else {
location. href =" view. php? Aid = {Dede: field name = 'id'/} & pageno = "+ (npage + 1 );
}< BR >}< br>
In this JS script, we define a method called gonextpic to switch to the next image.
3. Finally, modify the image output code and call the gonextpic method.
modify include/inc_channel_unit.php
to find "// All list or paging Gallery.
the modification is similar. (You need to modify the code several times ):
$ revalue = "

$ alt
\ r \ n ";
:
$ revalue = "
$ alt
";
the end. have fun!
