[英]comparing two variables using IF/IF..ELSE statement for PHP and inserting into MYSQL
我正在对两个变量进行计数验证,值为$ 7的$ row2和值为11的$ row3。我想要实现的是,只能将较高的值插入数据库。 现在的问题是$ row3的值大于$ row2。 但是,它总是将$ row2值插入数据库。 验证码有问题吗?
function tweetCount($hashtag) {
$url = 'http://search.twitter.com/search.atom?q='.urlencode($hashtag).'&rpp=100&result_type=recent';
//echo "<p>Connecting to <strong>$url</strong> ...</p>";
$ch = curl_init($url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, TRUE);
$xml = curl_exec ($ch);
curl_close ($ch);
//If you want to see the response from Twitter, uncomment this next part out:
//echo "<p>Response:</p>";
//echo "<pre>".htmlspecialchars($xml)."</pre>";
$affected = 0;
$twelement = new SimpleXMLElement($xml);
foreach ($twelement->entry as $entry) {
$text = trim($entry->title);
$author = trim($entry->author->name);
$time = strtotime($entry->published);
$id = $entry->id;
//echo count($entry->text);
// echo "<em>Posted ".date('n/j/y g:i a',$time)."</em><p>Tweet from <b><u>".$author."</u></b>: <strong>".$text."</strong> </p>";
//echo "<br/>";
}
//echo count($twelemtnt);
//echo count($entry);
echo $number_of_tweets = count($twelement->entry);
}
在我的html表上,我像这样回显数据:
<?php echo tweetCount($row[2]); ?>
<input type="hidden" name="row2" value="<?php echo tweetCount($row2[2]);?>" />
<input type="hidden" name="row2Ini" value="<?php echo $row2[1];?>" />
<input type="hidden" name="row2Sch" value="<?php echo $row2[2];?>" />
使用POST表单,我将其发布到另一个页面,我需要在其中进行计数验证,以查看哪个变量$ row2或$ row3具有更高的计数值,然后将更高的值插入数据库
admin.php页面
$row2 = $_POST['row2'];
$row2Ini = $_POST['row2Ini'];
$row2Sch = $_POST['row2Sch'];
if ( $row2 > $row3 )
{
echo "<br>row2 is more than row 3";
$con = mysql_connect("localhost","root","password");
if (!$con)
{ die('Could not connect: ' . mysql_error());}
mysql_select_db("schoutweet", $con);
$sql2="INSERT INTO matchTable (schInitial, schName,position)VALUES
('$_POST[row2Ini]','$_POST[row2Sch]','top4')";
if (!mysql_query($sql2,$con)){die('Error: ' . mysql_error());}echo "ROW2 record added!<BR>";
mysql_close($con);
}
else if ($row2 < $row3)
{
echo "row3 count is more than row 2";
$con = mysql_connect("localhost","root","password");
if (!$con)
{ die('Could not connect: ' . mysql_error());}
mysql_select_db("schoutweet", $con);
$sql="INSERT INTO matchTable (schInitial, schName,position)VALUES('$_POST[row3Ini]','$_POST[row3Sch]','top4')";
if (!mysql_query($sql,$con)){die('Error: ' . mysql_error());}echo "ROW3 record added!<BR>";
mysql_close($con);
}
永远不要写两次连接...您应该从if..else语句中删除连接部分...
检查下面是否可行...
$con = mysql_connect("localhost","root","password");
if (!$con)
{ die('Could not connect: ' . mysql_error());}
mysql_select_db("schoutweet", $con);
if ( $row2 > $row3 )
{
echo "<br>row2 is more than row 3";
$sql2="INSERT INTO matchTable (schInitial, schName,position)VALUES
('$_POST[row2Ini]','$_POST[row2Sch]','top4')";
if (!mysql_query($sql2,$con)){die('Error: ' . mysql_error());}echo "ROW2 record added!<BR>";
}
else
{
$sql="INSERT INTO matchTable (schInitial, schName,position)VALUES('$_POST[row3Ini]','$_POST[row3Sch]','top4')";
if (!mysql_query($sql,$con)){die('Error: ' . mysql_error());}echo "ROW3 record added!<BR>";
}
mysql_close($con);
