PHP foreach回声问题 [英] Php foreach echo issue
问题描述
我有这个代码，它为我生成一个数字，该数字等于我在星级评定系统数据库中的 ID 数量.
这段代码为我获得的每个 id 生成一个五星投票，但问题是，它在一个 div 中生成它们，而我在不同的 div 中特别需要它们.让我们假设我在一个 div 信息中为我得到的每个女主人打印出来，我用以下代码打印出她们的照片和姓名:
$sql =" select * from hostess";$query = mysql_query($sql);while ($row = mysql_fetch_array($query)) {回声<div id='照片'>";echo "<div id='图片'>";echo "<div id='scotch'><img src='images/Scotch.png'></div>";echo "<td> <img src=foto/photo1/".$row['photo'] ."></td>";echo "</div>";echo "";回声'<td><a href="hostess.php?id='.$row['id'].'">'.$row['first_name_en']." ".$row['family_name_en']."</a></td>";echo "</div>";echo "</div>";echo "<div id='photo2'>";echo "<div id='图片'>";echo "";echo '<form action="index.php" method="post" >';echo "<label>Notes</label></br><textarea>".$row['courrent_occupation'] ."</textarea></br>";echo '<input type="submit" value="edit" name="edit"></div>';echo "</div>";echo "";echo "<label>profile</label></br><textarea>".$row['profile_en'] ."</textarea>";echo "</div>";echo "</div>";}?>现在，我有另一个 php，它为我生成所有女主人 id 的所有星级
<?php//开始循环数据foreach($arr_star 作为 $star){ ?><h2>星级评分 - <?php echo $star['id'];?></h2><ul class='star-rating' id="star-rating-<?php echo $star['id'];?>"><?php/* getRating($id) 是生成当前评分 */?><li class="current-rating" id="current-rating-<?php echo $star['id'];?>"style="width:<?php echo getRating($star['id'])?>%"><!-- 将显示当前评级 --></li><?php/* 我们需要为星级评分生成id"..这个id"将标识要执行的数据 *//* 稍后我们将在 ajax 中传递它 */?><span class="ratelinks" id="<?php echo $star['id'];?>"><li><a href="javascript:void(0)" title="1 星，共 5 颗" class="one-star">1</a></li><li><a href="javascript:void(0)" title="5 星中的 1 星半" class="one-star-half">1.5</a></li><li><a href="javascript:void(0)" title="2 颗星，共 5 颗星" class="两颗星">2</a></li><li><a href="javascript:void(0)" title="2 星半(满分 5 分)" class="two-star-half">2.5</a></li><li><a href="javascript:void(0)" title="3 颗星，共 5 颗星" class="三颗星">3</a></li><li><a href="javascript:void(0)" title="5 分之三星半" class="三星半">3.5</a></li><li><a href="javascript:void(0)" title="4 颗星，共 5 颗星" class="四颗星">4</a></li><li><a href="javascript:void(0)" title="5 分之四星半" class="四星半">4.5</a></li><li><a href="javascript:void(0)" title="5 颗星，共 5 颗星" class="五颗星">5</a></li></span><?php } ?>
我需要的是分配每个女主人的个人资料，我打印他们的系统评级.我尝试在第一个脚本中插入 foreach，但它只显示一个配置文件，而不是所有配置文件.
fetchstar() 代码是:
function fetchStar(){$sql = "select * from `hostess`";$result=@mysql_query($sql);while($rs = @mysql_fetch_array($result,MYSQL_ASSOC)){$arr_data[] = $rs;}返回 $arr_data;}
解决方案 首先，您可能不应该使用 SELECT *.除此之外，我会将两个查询结合起来，您必须使用 MySQL 返回一个多维数组，然后对每个循环使用嵌套来回显您想要的数据.
这里有人为我回答了类似的问题.
遍历 MySQLphp 中的左连接 vs. 2 个单独的查询
$sql =" select * from hostess";$query = mysql_query($sql);while ($row = mysql_fetch_array($query)) {如果 ($lastID <> $row['id']) {$lastID = $row['id'];$hostess[$lastID] = array('id' => $row['id'],'first_name_en' =>$row['first_name_en'],等等'arr_star' =>大批() );}$hostess[$lastID]['arr_star'][] = array('star_id' => $row['star_id'] etc);}
然后你会为每个语句使用嵌套
for each($row as $rows){//回显你的女主人信息对于每个($arr_star 作为 $star){//echo你的星级信息}}
I have this code which produces me a number which is equal to the number of id's i've got in my database of star rating system.
This code generates me a five star voting for each id i've got, but the problem is, it generates them all in a div, while i need them specifically in different div's. let's suppose i print out in a div information for each hostess i've got, i print out their photo and name with the following code:
$sql =" select * from hostess";
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) {
echo "<div id='photo'>";
echo "<div id='picture'>";
echo "<div id='scotch'><img src='images/Scotch.png'></div>";
echo "<td> <img src=foto/photo1/".$row['photo'] . "></td>";
echo "</div>";
echo "<div id='text'>";
echo '<td><a href="hostess.php?id='.$row['id'].'">'. $row['first_name_en']." ". $row['family_name_en']."</a></td>";
echo "</div>";
echo "</div>";
echo "<div id='photo2'>";
echo "<div id='picture'>";
echo "<div id='notes'>";
echo '<form action="index.php" method="post" >';
echo "<label>Notes</label></br><textarea>".$row['courrent_occupation'] . "</textarea></br>";
echo '<input type="submit" value="edit" name="edit"></div>';
echo "</div>";
echo "<div id='notes'>";
echo "<label>profile</label></br><textarea>".$row['profile_en'] . "</textarea>";
echo "</div>";
echo "</div>";
}
?>
</div>
Now, i've got this other php which generates me all the star ratings for all hostess id's
<?php
// include update.php
include_once 'update.php';
// get all data from tabel
$arr_star = fetchStar();
?>
<?php
// start looping datas
foreach($arr_star as $star){ ?>
<h2>Star Rater - <?php echo $star['id'];?></h2>
<ul class='star-rating' id="star-rating-<?php echo $star['id'];?>">
<?php /* getRating($id) is to generate current rating */?>
<li class="current-rating" id="current-rating-<?php echo $star['id'];?>" style="width:<?php echo getRating($star['id'])?>%"><!-- will show current rating --></li>
<?php
/* we need to generate 'id' for star rating.. this 'id' will identify which data to execute */
/* we will pass it in ajax later */
?>
<span class="ratelinks" id="<?php echo $star['id'];?>">
<li><a href="javascript:void(0)" title="1 star out of 5" class="one-star">1</a></li>
<li><a href="javascript:void(0)" title="1 star and a half out of 5" class="one-star-half">1.5</a></li>
<li><a href="javascript:void(0)" title="2 stars out of 5" class="two-stars">2</a></li>
<li><a href="javascript:void(0)" title="2 star and a half out of 5" class="two-star-half">2.5</a></li>
<li><a href="javascript:void(0)" title="3 stars out of 5" class="three-stars">3</a></li>
<li><a href="javascript:void(0)" title="3 star and a half out of 5" class="three-star-half">3.5</a></li>
<li><a href="javascript:void(0)" title="4 stars out of 5" class="four-stars">4</a></li>
<li><a href="javascript:void(0)" title="4 star and a half out of 5" class="four-star-half">4.5</a></li>
<li><a href="javascript:void(0)" title="5 stars out of 5" class="five-stars">5</a></li>
</span>
</ul>
<?php } ?>
What i need is to assign each hostess profile i print their system rating.
I try to insert the foreach inside the first script but it then shows me just one profile, not all profiles.
The fetchstar() code is:
function fetchStar(){
$sql = "select * from `hostess`";
$result=@mysql_query($sql);
while($rs = @mysql_fetch_array($result,MYSQL_ASSOC)){
$arr_data[] = $rs;
}
return $arr_data;
}
解决方案 First, you probably shouldn't use SELECT *. That aside I would combine the two queries you have to return a multidimensional array with MySQL and then use nested for each loops to echo out the data you want.
Someone answered a similar question for me here.
Looping through MySQL left join in php vs. 2 separate queries
$sql =" select * from hostess";
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) {
if ($lastID <> $row['id']) {
$lastID = $row['id'];
$hostess[$lastID] = array('id' => $row['id'],
'first_name_en' => $row['first_name_en'],
etc
'arr_star' => array() );
}
$hostess[$lastID]['arr_star'][] = array('star_id' => $row['star_id'] etc);
}
Then you would use nested for each statements
for each($row as $rows){
//echo your hostess information
for each ($arr_star as $star){
//echo your star rating information
}
}
