未定义PHP函数错误和错误的</p>语法错误在生成的HTML中 [英] PHP function is not defined error and syntax error of misplaced </p> in generated HTML
问题描述
要解决棘手的Wiki搜索问题我们已经在PHP文件中实现了Javascript解决方案.
To solve a tricky wiki search problem we've implemented a Javascript solution in a PHP file.
不幸的是，我有两个问题.其一是未调用该函数，其次，我在错误控制台中看到无法解决的语法错误.首先，这是PHP文件中的代码:
Unfortunately, I have two problems. One is that the function is not being called and secondly I see a syntax error in the Error Console that I cannot solve. First, here is the code within the PHP file:
$htmlOut .= <<<ENDOFBLOCK
<script language="javascript">
function appendAndSubmit(){
var platform1 = document.getElementById( 'p1').checked;
var platform2 = document.getElementById( 'p2').checked;
var text = document.getElementById('search').value;
if (platform1) text = 'Applies to=Platform 1.0 ' + text;
if (platform2) text = 'Applies to=Platform 2.0 ' + text;
alert( text);
document.getElementById('search').value = text;
document.forms['searchform'].submit();}
</script>
ENDOFBLOCK
;
因此，第一个问题是我在错误控制台中看到 appendAndSubmit未定义.
So, the first problem is that I see appendAndSubmit is not defined in the Error Console.
第二个问题是语法错误.生成的HTML源是:
The second problem is the syntax error. The generated HTML source is:
<p><script language="javascript">
function appendAndSubmit(){
var platform1 = document.getElementById( 'p1').checked;
var platform2 = document.getElementById( 'p2').checked;
var text = document.getElementById('search').value;
if (platform1) text = 'Applies to=Platform 1.0 ' + text;
if (platform2) text = 'Applies to=Platform 2.0 ' + text;
alert( text);
document.getElementById('search').value = text;
document.forms['searchform'].submit();}
</p>
</script><div align="center" style="background-color:transparent"><form name="searchbox" id="searchbox" class="searchbox" action="/wiki/index.php?title=Special:Search"><input class="searchboxInput" name="search" type="text" value="" size="50" /><br /><input type="checkbox" name="1" value=""Applies to=Platform 1.0"" id="p1" /> <label for="">Platform 1.0</label><input type="checkbox" name="2" value=""Applies to=Platform 2.0"" id="p2" /> <label for="">Platform 2.0</label><br /><input type="submit" name="fulltext" class="searchboxSearchButton" value="Go!" onClick="appendAndSubmit();" /></div></form>
请注意，</p>出现在</script>之前，而<p>出现在<script>之前.
Note the </p> occurs before </script>, whereas <p> occurs before <script>.
有人可以告诉我我在做什么错吗?
Can anyone tell me please what I'm doing wrong?
对appendAndSubmit函数的调用在这里:
The call to the appendAndSubmit function is here:
$htmlOut .= Xml::element( 'input',
array(
'type' => 'submit',
'name' => 'fulltext',
'class' => 'searchboxSearchButton',
'value' => 'Go!',
'onClick' => 'appendAndSubmit();'
)
);
完整方法:
public function getSearchPlatform() {
// Use button label fallbacks
global $wgContLang;
// Use button label fallbacks
if ( !$this->mButtonLabel ) {
$this->mButtonLabel = wfMsgHtml( 'tryexact' );
}
if ( !$this->mSearchButtonLabel ) {
$this->mSearchButtonLabel = wfMsgHtml( 'searchfulltext' );
}
$htmlOut .= <<<ENDOFBLOCK
<script type="text/javascript">
function appendAndSubmit(){
var platform1 = document.getElementById( 'p1').checked;
var platform2 = document.getElementById( 'p2').checked;
var text = document.getElementById('search').value;
if (platform1) text = 'Applies to=Platform 3.0 ' + text;
if (platform2) text = 'Applies to=Platform 4.0 ' + text;
alert( text);
document.getElementById('search').value = text;
document.forms['searchform'].submit();}
</script>
ENDOFBLOCK
;
// Build HTML
$htmlOut .= Xml::openElement( 'div',
array(
'align' => 'center',
'style' => 'background-color:' . $this->mBGColor
)
);
$htmlOut .= Xml::openElement( 'form',
array(
'name' => 'searchbox',
'id' => 'searchbox',
'class' => 'searchbox',
'action' => SpecialPage::getTitleFor( 'Search' )->escapeLocalUrl(),
)
);
$htmlOut .= Xml::element( 'input',
array(
'class' => 'searchboxInput',
'name' => 'search',
'type' => 'text',
'value' => $this->mDefaultText,
'size' => $this->mWidth,
)
);
$htmlOut .= $this->mBR;
// Checkbox
$htmlOut .= Xml::element( 'input',
array(
'type' => 'checkbox',
'name' => '1',
'value' => '"Applies to=Platform 1.0"',
'id' => 'p1'
)
);
// Label
$htmlOut .= ' ' . Xml::label( 'Platform 2.0' );
// Checkbox
$htmlOut .= Xml::element( 'input',
array(
'type' => 'checkbox',
'name' => '2',
'value' => '"Applies to=Platform 2.0"',
'id' => 'p2'
)
);
// Label
$htmlOut .= ' ' . Xml::label( 'Platform 2.0' );
// Line break
$htmlOut .= $this->mBR;
$htmlOut .= Xml::element( 'input',
array(
'type' => 'submit',
'name' => 'fulltext',
'class' => 'searchboxSearchButton',
'value' => 'Go!',
'onClick' => 'appendAndSubmit();'
)
);
// Hidden fulltext param for IE (bug 17161)
if( $type == 'fulltext' ) {
$htmlOut .= Xml::hidden( 'fulltext', 'Search' );
}
$htmlOut .= Xml::closeElement( 'div' );
$htmlOut .= Xml::closeElement( 'form' );
// Return HTML
return $htmlOut;
}
推荐答案
通过将<script>和</script>之间的所有内容都放在一行上，我设法摆脱了</p>问题.当我将文件放在Linux服务器上时，这使我想知道编辑器是否存在问题(Windows上为Notepad ++).但是我认为Notepad ++可以解决这个问题(对于PHP来说这没问题).
I managed to get rid of the </p> problem by putting everything between <script> and </script> on one line. This makes me wonder if it is a problem with the editor (Notepad++ on Windows) when I put the file on the Linux server. But I thought Notepad++ could handle that (it is no problem for PHP).
The fact that the script was not being called was actually due to a syntax error, which I found out via a clue in another question: 'search' should have been 'searchbox'.
一旦解决，函数将被正确调用.
Once that was resolved the function was called without errors.
万一其他人想要，这里是完整的工作代码:
In case anyone else wants it, here is the complete working code:
public function getSearchPlatform() {
// Use button label fallbacks
global $wgContLang;
// Use button label fallbacks
if ( !$this->mButtonLabel ) {
$this->mButtonLabel = wfMsgHtml( 'tryexact' );
}
if ( !$this->mSearchButtonLabel ) {
$this->mSearchButtonLabel = wfMsgHtml( 'searchfulltext' );
}
$htmlOut .= <<<ENDOFBLOCK
<script type="text/javascript">function appendAndSubmit(){var platform1 = document.getElementById('p1').checked;var platform2 = document.getElementById('p2').checked;var text = document.getElementById('searchboxInput').value;if (platform1 * platform2 >0) text = text + ' "Applies to=Platform 1.0" "Applies to=Platform 2.0"';else if (platform1) text = text + ' "Applies to=Platform 1.0"';else if (platform2) text = text + ' "Applies to=Platform 2.0"';document.getElementById('searchboxInput').value = text;document.forms['searchform'].submit();}</script>
ENDOFBLOCK;
// Build HTML
$htmlOut .= Xml::openElement( 'div',
array(

// Checkbox
$htmlOut .= Xml::element( 'input',
