在玩论坛的站长朋友,每次发文章标题都受字数的限制,一直找不到解决的办法,此教程为云墨亲自测试的经验总结,今天就分享给大家。
下面由源码专家技术分享解决标题限制80字符方法步骤:

一、数据库修改;
二、修改JS验证字符数文件;
三、修改模板中写死的字符限制数;
四,修改函数验证文件;
五,修改语言包文件。
一、数据库修改,修改数据库标题字段的长度为200字符:运行下面的sql语句:
(注意修改你的表的前缀)
  1. ALTER TABLE `pre_forum_post` CHANGE `subject` `subject` VARCHAR(200) NOT NULL;
  2. ALTER TABLE `pre_forum_rsscache` CHANGE `subject` `subject` char(200) NOT NULL;
  3. ALTER TABLE `pre_forum_thread` CHANGE `subject` `subject` char(200) NOT NULL;
复制代码

二、修改JS验证字符数:
1、找到文件static/js/forum_post.js的75-81行
  1. if(($('postsubmit').name != 'replysubmit' && !($('postsubmit').name == 'editsubmit' && !isfirstpost) && theform.subject.value == "") || !sortid && !special && trim(message) == "") {
  2.                 showError('抱歉,您尚未输入标题或内容');
  3.                 return false;
  4.         } else if(mb_strlen(theform.subject.value) > 80) {
  5.                 showError('您的标题超过 80 个字符的限制');
  6.                 return false;
  7.         }
复制代码


修改为:
  1. if(($('postsubmit').name != 'replysubmit' && !($('postsubmit').name == 'editsubmit' && !isfirstpost) && theform.subject.value == "") || !sortid && !special && trim(message) == "") {
  2.                 showError('抱歉,您尚未输入标题或内容');
  3.                 return false;
  4.         } else if(mb_strlen(theform.subject.value) > 200) {
  5.                 showError('您的标题超过 200 个字符的限制');
  6.                 return false;
  7.         }
复制代码


2、找到文件sitatic/js/forum.js的212到218行代码:
  1. if(theform.message.value == '' || theform.subject.value == '') {
  2.                 s = '抱歉,您尚未输入标题或内容';
  3.                 theform.message.focus();
  4.         } else if(mb_strlen(theform.subject.value) > 80) {
  5.                 s = '您的标题超过 80 个字符的限制';
  6.                 theform.subject.focus();
  7.         }
复制代码


修改为:
  1. if(theform.message.value == '' || theform.subject.value == '') {
  2.                 s = '抱歉,您尚未输入标题或内容';
  3.                 theform.message.focus();
  4.         } else if(mb_strlen(theform.subject.value) > 80) {
  5.                 s = '您的标题超过 80 个字符的限制';
  6.                 theform.subject.focus();
  7.         }
复制代码

三、修改模板中写死的字符限制数:
1、找到文件\template\default\forum\post_editor_extra.htm的25到33行:
  1. <!--{if $_GET[action] != 'reply'}-->
  2. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160;&#160;<span><input type="text" name="subject" id="subject" class="px" value="$postinfo[subject]" {if $_GET[action] == 'newthread'}onblur="if($('tags')){relatekw('-1','-1'{if $_G['group']['allowposttag']},function(){extraCheck(4)}{/if});doane();}"{/if} onkeyup="strLenCalc(this, 'checklen', 80);" style="width: 25em" tabindex="1" /></span>
  3. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;<!--{else}-->
  4. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160;&#160;<span id="subjecthide" class="z">RE: $thread[subject] [<a href="javascript:;" onclick="display('subjecthide');display('subjectbox');$('subject').value='RE: {echo dhtmlspecialchars(str_replace('\'', '\\\'', $thread[subject]))}';display('subjectchk');strLenCalc($('subject'), 'checklen', 80);return false;">{lang modify}</a>]</span>
  5. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160;&#160;<span id="subjectbox" style="display:none"><input type="text" name="subject" id="subject" class="px" value="" onkeyup="strLenCalc(this, 'checklen', 80);" style="width: 25em" /></span>
  6. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;<!--{/if}-->
  7. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;<span id="subjectchk"{if $_GET[action] == 'reply'} style="display:none"{/if}>{lang comment_message1} <strong id="checklen">80</strong> {lang comment_message2}</span>
  8. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;<script type="text/javascript">strLenCalc($('subject'), 'checklen', 80)</script>
  9. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160; <!--{/if}-->
复制代码


修改为:
  1. <!--{if $_GET[action] != 'reply'}-->
  2. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160;&#160;<span><input type="text" name="subject" id="subject" class="px" value="$postinfo[subject]" {if $_GET[action] == 'newthread'}onblur="if($('tags')){relatekw('-1','-1'{if $_G['group']['allowposttag']},function(){extraCheck(4)}{/if});doane();}"{/if} onkeyup="strLenCalc(this, 'checklen', 200);" style="width: 25em" tabindex="1" /></span>
  3. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;<!--{else}-->
  4. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160;&#160;<span id="subjecthide" class="z">RE: $thread[subject] [<a href="javascript:;" onclick="display('subjecthide');display('subjectbox');$('subject').value='RE: {echo dhtmlspecialchars(str_replace('\'', '\\\'', $thread[subject]))}';display('subjectchk');strLenCalc($('subject'), 'checklen', 200);return false;">{lang modify}</a>]</span>
  5. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160;&#160;<span id="subjectbox" style="display:none"><input type="text" name="subject" id="subject" class="px" value="" onkeyup="strLenCalc(this, 'checklen', 200);" style="width: 25em" /></span>
  6. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;<!--{/if}-->
  7. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;<span id="subjectchk"{if $_GET[action] == 'reply'} style="display:none"{/if}>{lang comment_message1} <strong id="checklen">200</strong> {lang comment_message2}</span>
  8. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;<script type="text/javascript">strLenCalc($('subject'), 'checklen', 200)</script>
  9. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160; <!--{/if}-->
复制代码

2、找到文件\template\default\forum\forumdisplay_fastpost.htm31-32行:
  1. <input type="text" id="subject" name="subject" class="px" value="" onkeyup="strLenCalc(this, 'checklen', 80);" tabindex="11" style="width: 25em" />
  2. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160;&#160;<span>{lang comment_message1} <strong id="checklen">80</strong> {lang comment_message2}</span>
复制代码

修改为:
  1. <input type="text" id="subject" name="subject" class="px" value="" onkeyup="strLenCalc(this, 'checklen', 200);" tabindex="11" style="width: 25em" />
  2. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160;&#160;<span>{lang comment_message1} <strong id="checklen">200</strong> {lang comment_message2}</span>
复制代码

四,修改函数验证提示:
找到文件source/function/function_post.php的361-363行:
  1. if(dstrlen($subject) > 80) {
  2. &#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160;&#160; &#160; return 'post_subject_toolong';
  3. &#160; &#160;&#160; &#160;&#160;&#160;}
复制代码


修改为:
  1. if(dstrlen($subject) > 200) {
  2. return 'post_subject_toolong';
  3. }
复制代码

五、找到语言包提示文字,打开 source/language/lang_messege.php 并找到998行改为:
  1. 'post_subject_toolong' => '抱歉,您的标题超过 80 个字符修改标题长度',
复制代码

修改为:
  1. 'post_subject_toolong' => '抱歉,您的标题超过 200 个字符修改标题长度',
复制代码

我觉得,80字完全够了,这仅仅只是个标题而已,字太多反而不精练

注意是80字节不是80个字,要是80个汉字就好了
