| 19 | # |
|---|
| 20 | # Usage: |
|---|
| 21 | # 1. Put this command at the top of your PERL program: |
|---|
| 22 | # |
|---|
| 23 | # use FCKeditor; |
|---|
| 24 | # |
|---|
| 25 | # 2. Where you want to place the FCKeditor in your output, |
|---|
| 26 | # call FCKeditor::create() as follows: |
|---|
| 27 | # |
|---|
| 28 | # $html_string = FCKeditor::create($InstanceName,$BasePath); |
|---|
| 29 | # |
|---|
| 30 | # This will produce an HTML string which effectively replaces |
|---|
| 31 | # a <textarea name=$InstanceName></textarea> field in your form. |
|---|
| 32 | # Note that there are a few other parameters which you can |
|---|
| 33 | # specify in the create() call, noted below. Height and |
|---|
| 34 | # width, for example. |
|---|
| 35 | # |
|---|
| 36 | # You can then integrate this HTML code directly into your |
|---|
| 37 | # Output. For example: |
|---|
| 38 | # |
|---|
| 39 | # use FCKeditor; |
|---|
| 40 | # print 'content-type: text/html\n\n'; |
|---|
| 41 | # print '<html><body><form method=get action="this.pl">'; |
|---|
| 42 | # print '<p>Enter Your Message Here:</p>'; |
|---|
| 43 | # print FCKeditor::create(); |
|---|
| 44 | # print '<input type=submit name="OK" value="OK">'; |
|---|
| 45 | # print '</form></body></html>'; |
|---|
| 46 | # |
|---|
| 47 | # Or you could send the string to the Template module, |
|---|
| 48 | # depending on how you output your HTML. Your return CGI |
|---|
| 49 | # program will then look for a parameter "editor", which is |
|---|
| 50 | # the default (see $InstanceName). |
|---|
