php - meeplace 中的语法错误

Question

我一直在与 meeplace 合作，我遇到了关于代码中的语法错误的问题。它在广告管理页面中：

echo "<option value='0'>AM</option>";
echo "<option value='12' ".$select.">PM</option>";

echo " </select></td>\r\n </tr>\r\n \r\n <tr>\r\n <td align=\"right\">Total Views Allowed:</td>\r\n <td><input type=\"text\" id=\"ad_total_views\" style=\"width:50px;\" value=\"\" disabled=\"disabled\" /> <label><input type=\"checkbox\" checked=\"checked\" onclick=\"if(this.checked==true){$('#ad_total_views').val('');$('#ad_total_views').attr('disabled','disabled');}else{$('#ad_total_views').val('');$('#ad_total_views').removeAttr('disabled');$('#ad_total_views').focus()}\" />Unlimited</label></td>\r\n </tr>\r\n \r\n <tr>\r\n <td align=\"right\">Total Clicks Allowed:</td>\r\n <td><input type=\"text\" id=\"ad_total_clicks\" style=\"width:50px;\" value=\"\" disabled=\"disabled\" /> <label><input type=\"checkbox\" checked=\"checked\" onclick=\"if(this.checked==true){$('#ad_total_clicks').val('');$('#ad_total_clicks').attr('disabled','disabled');}else{$('#ad_total_clicks').val('');$('#ad_total_clicks').removeAttr('disabled');$('#ad_total_clicks').focus()}\" />Unlimited</label></td>\r\n </tr>\r\n </table></td>\r\n </tr>\r\n <tr bgcolor=\"#FFFFFF\">\r\n <td class=\"td_th\" align=\"center\">Smarty Code (Developer)</td>\r\n <td>{\$ads->getAdCode(<span id=\"smartycode\">1</span>)}</td>\r\n </tr>\r\n <tr bgcolor=\"#FFFFFF\">\r\n <td class=\"td_th\" align=\"center\">&nbsp;</td>\r\n <td><input type=\"button\" value=\"Create New Campaign\" onclick=\"new_ad()\" /></td>\r\n </tr>\r\n </TBODY></TABLE>\r\n<br />\r\n\r\n<TABLE cellSpacing=1 cellPadding=4 width=\"100%\" border=0>\r\n <TBODY>\r\n <TR class=\"td_title\">\r\n <TD colSpan=7>Ad Campaigns</TD></TR>\r\n <TR bgColor=#ffffff>\r\n \r\n <TD width=\"10%\" align=\"center\" class=\"td_th\">&nbsp;</TD>\r\n <TD width=\"4%\" align=\"center\" class=\"td_th\">ID</TD>\r\n <TD width=\"29%\" align=\"center\" class=\"td_th\">Campaign Name</TD>\r\n <TD width=\"12%\" align=\"center\" class=\"td_th\">Start Date</TD>\r\n <TD width=\"11%\" align=\"center\" class=\"td_th\">End Date</TD>\r\n <TD width=\"17%\" align=\"center\" class=\"td_th\">Viewed / Views Allowed</TD>\r\n <TD width=\"17%\" align=\"center\" class=\"td_th\">Clicked / Clicks Allowed</TD>\r\n </TR>\r\n ";

我不太确定出了什么问题，错误出现在上面的第三行代码中。

Parse error: syntax error, unexpected '(', expecting T_VARIABLE or '$' in /mgt/body/ad_list.php on line 185

如果其他人遇到过这个问题或知道一个简单的答案来解决这个问题，那就太好了。我已经尝试了一些事情，比如让它不止一条线，但没有运气！：秒

更新

我设法将问题缩小到这一点：

     <label><input type=\"checkbox\" checked=\"checked\" onclick=\"if(this.checked==true){$('#ad_total_views').val('');$('#ad_total_views').attr('disabled','disabled');}else{$('#ad_total_views').val('');$('#ad_total_views').removeAttr('disabled');$('#ad_total_views').focus()}\" />Unlimited</label></td>\r\n 

Answer 1

这是很久以来看到的一个疯狂echo的..我建议你使用Heredoc

例子

$str = <<<EOD
Example of string
spanning multiple lines
using heredoc syntax.
EOD;

echo $str ;

回到你的脚本

<?php
$select ="test";
echo "<option value='0'>AM</option>";
echo "<option value='12' " . $select . ">PM</option>";
echo <<<DATA

</select>

试试这个：

echo ' </select></td>'."\r\n".' </tr>'."\r\n".' '."\r\n".' <tr>'."\r\n".' <td align="right">Total Views Allowed:</td>'."\r\n".' <td><input type="text" id="ad_total_views" style="width:50px;" value="" disabled="disabled" /> <label><input type="checkbox" checked="checked" onclick="if(this.checked==true){$(\'#ad_total_views\').val(\'\');$(\'#ad_total_views\').attr(\'disabled\',\'disabled\');}else{$(\'#ad_total_views\').val(\'\');$(\'#ad_total_views\').removeAttr(\'disabled\');$(\'#ad_total_views\').focus()}" />Unlimited</label></td>'."\r\n".' </tr>'."\r\n".'

';

PHP 可能会因为字符串中的 $ 而感到困惑，因为它是一个双引号字符串，并且$被解析为该字符串内的变量开始。
