【问题描述】:
我想用表格中显示的这些点显示调查。
survey_classType_pokemon_table
idquestion idclassType idPokemon
8 | 13 | 14
8 | 13 | 15
8 | 14 | 16
8 | 15 | 17
8 | 15 | 18
8 | 15 | 19
这些是我拥有的表格:
surveyTable
idsurvey question
8 Choose one pokémon from each type
classTypeTable
idclassType classType
13 | Water
13 | Water
14 | Fire
15 | Grass
15 | Grass
15 | Grass
pokemonTable
idPokemon pokemon
14 | Squirtle
15 | Mudkip
16 | Charmander
17 | Bulbasaur
18 | Treecko
19 | Turtwig
我陷入了困境,因为我不断循环打印已经显示的数据并将其作为一个可能的选择。我想不出如何修正我的逻辑。
这是我目前的代码:
$sql2 = mysqli_query(" SELECT * FROM question_classType_pokemon_table where idsurvey='8' ") or die(mysqli_error());
?>
<div class="entry">
<form action="#" method="post">
<?php
$cont = 1;
$num = 1;
while($row = mysqli_fetch_assoc( $sql2 )) {
$idclasstype = $row['idclasstype'];
$idPokemon = $row['idPokemon'];
$result1 = mysqli_query("SELECT classType FROM ClassTypeTable where idclasstype='$idclasstype' ");
while($row = mysqli_fetch_array( $result1 )){
$classType = $row['classType'];
echo $classType."<br/>";
}
$sql3 = mysqli_query("SELECT pokemon FROM pokemonTable where idPokemon='$idPokemon'");
while($row1 = mysqli_fetch_assoc( $sql3 )){
${'opc'.$num} = $row1['pokemon'];
echo "<br/>";
echo "NUM: ".$num++."<br/>";
}
for($i = 1; $i < $num; $i++){
echo "<input type=\"radio\" name=\"".${'opc'.$cont}."\" value=\"".${'opc'.$i}."\">".${'opc'.$i}."<br/>";
}
$cont++;
}
?>
<input type="submit" value="SEND">
</form>
</div>
我得到的是:
Water
NUM: 1
Squirtle (radio button)
Water
NUM: 2
Squirtle (radio button)
Mudkip (radio button)
Fire
NUM: 3
Squirtle (radio button)
Mudkip (radio button)
Charmander (radio button)
Grass
NUM: 4
Squirtle (radio button)
Mudkip (radio button)
Charmander (radio button)
Bulbasaur (radio button)
Grass
NUM: 5
Squirtle (radio button)
Mudkip (radio button)
Charmander (radio button)
Bulbasaur (radio button)
Treecko (radio button)
Grass
NUM: 6
Squirtle (radio button)
Mudkip (radio button)
Charmander (radio button)
Bulbasaur (radio button)
Treecko (radio button)
Turtwig (radio button)
我想要的输出是:
Survey
Choose one pokémon from each type
Water (Choose one)
1. Squirtle (radio button)
2. Mudkip (radio button)
Fire (Choose one)
1. Charmander (radio button)
Grass (Choose one)
1. Bulbasaur (radio button)
2. Treecko (radio button)
3. Turtwig (radio button)
[SEND]
谁能帮我解决我的逻辑中的这个错误。
【问题讨论】:
-
我会从一本关于 PHP 和 MySQL 的好书或教程开始
-
stackoverflow 搜索也应该有很大帮助。
-
@HilmiErdemKEREN 我几乎到处都看过。但我找不到任何好的例子。
